nature
Silicon micro powder has high purity, excellent physical and chemical properties, and stable chemical properties. It is not easily reactive with other substances and does not react chemically with most acids and bases. The particle size distribution of silica micro powder is reasonable, which can reduce and eliminate sedimentation and stratification phenomena when used.


preparation
The main raw materials for the preparation of silica micro powder include quartz ore, silica, etc. By physical processing methods such as crushing and grinding, silica powder with smaller particle size can be obtained. In addition, organic surface modification can be carried out on silicon micro powder to improve its wettability and adsorption performance in various resins.


Application fields of silicon micro powder
Silicon micro powder has been widely used in various fields due to its excellent filling and reinforcing properties.


Ceramics: Silicon micro powder can be used as a raw material for ceramic products to improve the mechanical strength and wear resistance of ceramics.
Coatings: As a filler in coatings, silicon micro powder can improve the adhesion and weather resistance of coatings.
Rubber and Plastic: Silicon micro powder can enhance the tensile strength, compressive strength, and wear resistance of rubber and plastic.
Electrical products: As a filling material for electrical products, silicon micro powder can improve the insulation and heat resistance of the product.
In addition, silicon micro powder can also be used in fields such as glass manufacturing and refractory materials.
