What are the common uses of Silica?
Silica has a wide range of uses, and the common diameters are listed below:
First, in the metallurgical industry, it can be a flux. In ancient metallurgy, the removal of ore impurities is essential. When silica encounters high temperature, it combines with impurities such as iron oxide in the ore to form slag floating on the molten metal, which is easy to separate and improves the purity of the metal. Such as the iron of the sword, which is melted by silica, the impurities are removed and the quality is excellent, and the sword body is tough and sharp.
Second, in the glass industry, it is a key raw material. Silica is melted at high temperature and cooled into a glassy substance. In the past, when glazed, silica was used as the base, and various matching materials were added to make it into crystal clear glazed utensils, or for windows and windows, or for ornaments. All rely on the work of silica.
Third, in the chemical industry, it can make silica gel and other materials. Silica gel has strong water absorption and is often used as a desiccant. Although there is no refined silica gel in ancient times, the principle is the same. The silica-containing materials absorb moisture and prevent moisture, and protect precious books and utensils from moisture erosion.
Fourth, in the construction industry, it can be made into concrete aggregates. Sand and gravel are mixed with cement into concrete. The sand and gravel formed by silica make the concrete have good strength and durability. Ancient large-scale buildings were based on stone, and the stone contained more silica, which could not fall over the years and also relied on the characteristics of silica.

What are the physical properties of Silica?
The physical properties of silica are unique. Looking at its form, at room temperature, it often takes the shape of a solid state. Or it is in a crystalline state, such as crystal crystal clear, with an orderly structure; or it is in an amorphous form, like diatomaceous earth, with a relatively loose texture.
In terms of its color, pure silica is mostly colorless and transparent, just like clear water, without variegated colors. However, if it contains some impurities, it can also change into a different color, such as amethyst, which is magnificent purple due to its manganese, iron and other elements.
Besides its hardness, silica is quite hard, with a Mohs hardness of about 7 degrees. It can easily characterize lower hardness materials such as gypsum and calcite. This property makes it very useful in grinding, cutting and other fields.
As for the density, it is about 2.65 grams/cubic centimeter. Compared with many metals, the density is relatively small, but it is heavier than common lightweight materials such as wood.
The melting point of silica is extremely high, about 1713 ° C, and the boiling point is as high as 2230 ° C. Such a high melting point is due to the strong covalent bonds between its internal atoms, which make it very stable and difficult to be destroyed. And its chemical properties are stable. At room temperature and pressure, most common chemical reagents are difficult to react with, and only hydrofluoric acid can cause erosion.
Furthermore, silicon dioxide has poor thermal conductivity and is a poor conductor of heat. It can be used as a heat insulation material to resist heat transfer and protect the temperature difference between the inside and outside of the object. And its electrical insulation is also good, and current is difficult to pass through, which is also indispensable in the field of electrical insulation.

What are the chemical properties of Silica?
Silica is an important oxide of silicon. Its chemical properties are quite unique and have many wonderful properties.
First of all, it reacts with acids. Although silica is an acidic oxide, it does not interact with ordinary acids, but can only react with hydrofluoric acid. Its reaction formula is: $SiO_ {2} + 4HF = SiF_ {4}\ uparrow + 2H_ {2} O $. This reaction is different from normal conditions. In fact, due to the strong stability of silicon-fluorine bonds, it can form this unique reaction, which should also be the basis for etching glass.
Let's look at the reaction between it and alkali. Silicon dioxide can be phased with strong alkali in a volumetric manner, generating silicate and water. Taking sodium hydroxide as an example, its formula is: $SiO_ {2} + 2NaOH = Na_ {2} SiO_ {3} + H_ {2} O $. This should also highlight the nature of its acidic oxide, which is a key reaction in the industrial preparation of silicate substances.
And its reaction with salts. In high temperature environment, silica can react with some salts. If it is co-melted with sodium carbonate at high temperature, the formula should be: $SiO_ {2} + Na_ {2} CO_ {3}\ stackrel {high temperature Na_ {2} SiO_ {3} + CO_ {2}\ uparrow $. This reaction is very important in the glass manufacturing process and helps to form glass.
Furthermore, silica can react with carbon elemental matter at high temperature. The corresponding formula is: $SiO_ {2} + 2C\ stackrel {high temperature }{=\!=\!=} Si + 2CO\ uparrow $. This is the main method for industrial production of crude silicon. Carbon is used as a reducing agent to reduce the silicon in silica, which plays a key role in the preparation of semiconductor materials.
From this perspective, the chemical properties of silica are not only acidic oxides, but also unique in reacting with hydrofluoric acid. It is crucial in many industrial fields and is a wonderful substance.

What are the applications of Silica in industrial production?
Silicon is widely used in industrial production. In the industry of glass firing, it is also the base material. Co-melting of silica, soda ash, and limestone, silica in silica is combined with soda ash and limestone, and then becomes the main structure of glass. The light transmission, hardness, and corrosion resistance of glass are all due to the work of silicon. Such as the windows of palaces and the glass of cars and ships, they are all well used because of silicon.
In the production of ceramics, silicon is also indispensable. Clay contains silicon compounds, which are formed and fired, and silicide participates in the structure of the pottery body. The ability of ceramics to withstand high temperature and have beautiful decoration is the power of silicon. Ancient colored pottery and famous kiln porcelain are all brilliant because of silicon and passed down to later generations.
In metallurgy, silicon is used as a deoxidizer and alloying agent. When steelmaking, silicon is added to molten steel, and silicon and oxygen are affinity. In addition to oxygen in steel, the purity and strength of steel are increased. And silicon enters the steel to form an alloying element and change the properties of steel. For example, silicon steel sheet has good magnetic conductivity. It is used in motors and transformers to reduce energy consumption and improve efficiency.
Furthermore, in the electronics industry, silicon is a key material. Silicon single wafers are the substrate of integrated circuits, and the manufacture of chips is mostly based on silicon wafers. The semiconductivity of silicon allows electronic devices to control current and signals, making them the core of electronic products such as computers and mobile phones. In today's information age, the contribution of silicon is huge, and without silicon, there is no such thing as today's electronics.
In the chemical industry, silicon is also used in various ways. Silica gel has strong moisture absorption, is a commonly used desiccant, and is used in food and medicine for preservation and protection. And silicone rubber is resistant to high and low temperatures, aging, and is widely used in sealing and shock absorption, and is needed in aerospace, automotive and other industries. Therefore, silicon is very important in industrial production, and its work is everywhere.

Ancient colored pottery and famous kiln porcelain are all brilliant because of silicon and passed down to later generations.
In metallurgy, silicon is used as a deoxidizer and alloying agent. When steelmaking, silicon is added to molten steel, and silicon and oxygen are affinity. In addition to oxygen in steel, the purity and strength of steel are increased. And silicon enters the steel to form an alloying element and change the properties of steel. For example, silicon steel sheet has good magnetic conductivity. It is used in motors and transformers to reduce energy consumption and improve efficiency.
Furthermore, in the electronics industry, silicon is a key material. Silicon single wafers are the substrate of integrated circuits, and the manufacture of chips is mostly based on silicon wafers. The semiconductivity of silicon allows electronic devices to control current and signals, making them the core of electronic products such as computers and mobile phones. In today's information age, the contribution of silicon is huge, and without silicon, there is no such thing as today's electronics.
In the chemical industry, silicon is also used in various ways. Silica gel has strong moisture absorption, is a commonly used desiccant, and is used in food and medicine for preservation and protection. And silicone rubber is resistant to high and low temperatures, aging, and is widely used in sealing and shock absorption, and is needed in aerospace, automotive and other industries. Therefore, silicon is very important in industrial production, and its work is everywhere.
What are the advantages of Silica compared to other materials?
Silica is unique among all things. Its nature is firm and stable, unlike other things that are easily changed by the outside world. Ordinary materials, in case of cold, heat, dryness, or deformation, however, silica can still keep its authenticity in this environment, which is also beneficial.
And silica is very fire-resistant, and the flame burns without destroying it. Compared with all fire-resistant substances, when the fire is reached, it will melt, burn, and turn into nothing. Silica is calm in the fire, can be used as a kiln and a smelting tool, and keeps it safe in the high temperature. This is another good thing.
Furthermore, silica is very stable in chemistry. Other substances may be easily combined with various chemical agents, resulting in its non-quality. Silica, on the other hand, cannot be easily eroded or melted by various reagents, and can maintain its inherent state in complex chemical environments. Therefore, in chemical industries, it is often the material to rely on.
The effect of silica on light and electricity is also commendable. It can conduct light and has very little damage to light. Compared with other materials with poor light conductivity, it can make light travel farther and clearer. In electricity, although it is not a good conductor, it has excellent insulation performance, which is different from the quality of easy conduction, which can protect the safety of circuits and prevent leakage.
As for its wide range of uses, it is also difficult for various materials. It can be used as the cornerstone of the building to make the house stable; it can be made of glass, which is clear and translucent; in the electronics industry, it is the foundation of the chip and is related to the progress of technology. This is the special advantage of silica compared with other things. It is a God-given good material, and it has a great contribution to the world.
