Silica powder
Silica powder is pure and unique, and has a wide range of uses.
Application of silica powder
It is involved in all industries. In the field of metallurgy, it is often a deoxidizer. When put into the furnace, it can quickly remove the oxygen in the liquid metal, raise the purity of the metal, and make it stronger and tougher. For example, when casting steel, adding an appropriate amount of silica powder will increase the strength and corrosion resistance of the steel. It can be used to build bridges and buildings. It is very strong.
In the chemical industry, silica powder is also an important material. Synthesize special silicide, which is used to make sealants and lubricants, and has outstanding performance. The sealant can strictly block the gap and waterproof the invasion of gas; the lubricant can reduce the friction of the equipment, make it run smoothly and prolong the life.
Furthermore, in building materials, silicon powder is added to concrete to optimize its performance. It makes the concrete have good fluidity, easier to cast and form, and enhances its impermeability, which can resist the penetration of water. In hydraulic buildings, such as dams and pools, the effect is significant and it is not damaged for a long time.
Characteristics of Silicon Powder
Silicon powder is fine, with small particle size and uniform, its specific surface area is large, and its activity is high. The appearance is often gray and powdery, and the texture is light. It is chemically stable, and it is not easy to react with common substances at room temperature. However, in case of strong alkali, it can be combined with it to synthesize soluble silicate. Its thermal stability is also excellent, and it can keep its properties unchanged at high temperatures, so it is widely used in the field of high temperature operations.
Preparation of silica powder
There are many methods for preparing silica powder. One is the industrial silicon grinding method. High-quality industrial silicon blocks are collected, crushed, put into the grinding equipment, and finely ground to the required particle size to obtain silica powder. The silica powder obtained by this method has high purity and controllable particle size.
The second is the chemical vapor deposition method. Using silicon halide as raw material, in a high temperature and carrier gas environment, through chemical reaction, silicon is precipitated from the gaseous state and condensed into solid silicon powder. This silica powder has extremely fine particle size and high purity, and is mostly used in high-end electronic, optical materials and other fields to meet its strict requirements for high purity and fine particle size of silica powder.
