Silica Dioxide Applications Properties Production
On silica
Silica is a common substance in the world. It has a wide range of applications and unique properties. There are also methods for production.
Application
In the field of industry, silica has many uses. In glass manufacturing, it is the key raw material. Glass is clear and bright, thanks to the work of silica. After high temperature smelting, silica fuses with other things to form all kinds of glass products, such as glass in windows and windows, which is transparent to light; such as glass in appliances, beautiful and practical.
In the field of electronics, silica is also indispensable. In the manufacture of integrated circuits, silica is used as an insulating material. It can ensure the orderly conduction of current between electronic components, avoid the risk of short circuits, and make electronic devices operate stably. Such as the chip of the computer, the main board of the smart phone, all have silica silently at work.
In the construction industry, sand and gravel are rich in silica. Concrete is strong, sand and gravel are its important components. Mixing silica with cement enhances the strength of the building structure, making high-rise buildings stand up and stand for years.
Different properties
Silica has unique physical properties. Its texture is hard and Mohs hardness is quite high, so it can resist wear. Common quartz, the main component is silica, can still maintain its shape after years of rubbing. Its chemical properties are relatively stable, and it is difficult to react with many chemicals at room temperature. When exposed to strong bases, such as sodium hydroxide, it can react slowly to form sodium silicate and water. At high temperatures, it can react with reducing agents such as carbon to show the other side of its chemical activity.
Production Method
There are many ways to produce silica. Mining of natural ores is one of the methods. Quartz ore is an important source of silica. After mining, crushing, grinding and other processes, silica products of different particle sizes can be obtained. Chemical synthesis is also a commonly used method. If silane is used as raw material and oxidized by gas phase, high-purity silica can be obtained. The product obtained by this method has high purity and is suitable for electronics and other industries with strict purity requirements. Or by reacting water glass with acid, silica can also be obtained through precipitation, filtration, washing, drying and other steps. In conclusion, silica plays an important role in human production and life, and its application, properties, and production are all worthy of in-depth investigation to better serve social development.
