100 mesh metal silicon powder

100 mesh metal silicon powder is silver gray with metallic luster. It has high melting point, good heat resistance, high resistivity, and high anti-oxidation effect. It is called "industrial monosodium glutamate". It is an important basic industrial raw material and has a wide range of applications in many industries and fields. In the organosilicon chemical industry, 100-mesh metal silicon powder is the basic raw material for the synthesis of organosilicon polymers, such as trichlorosilane, an important intermediate for the production of silane coupling agents and other organosilicon products, and the main raw material for polysilicon. Silicon monomer, silicone oil, silicone rubber preservatives to improve the product's high temperature resistance, electrical insulation, corrosion resistance, waterproof and other characteristics.

 

In the metallurgical foundry industry, 100-mesh metal silicon powder is used as a non-ferrous base additive and a silicon steel alloy agent to improve the hardenability of steel. Metal silicon powder can also be used as a reducing agent for some metals, for new ceramic alloys, etc. The reactivity of 100-mesh metal silicon powder is not only related to the composition, proportion, and particle size, but also to its microstructure. Its processing method, appearance, particle shape, and particle size distribution have a significant impact on the yield of synthetic products and application effects. At present, the quality of ordinary silicon metal powder in the market is uneven, and the production lacks scientific formula and advanced powder making technology. Therefore, the production of metal silicon powder has the following shortcomings: poor activity, low product yield and low conversion rate.

 

The silicon content of 100-mesh metal silicon powder is more than 98%, wherein, based on the total mass of the metal silicon powder, the metal silicon powder contains 2-6 μ g/g of zinc, no more than 10 μ g/g of phosphorus, 80- 120 μg/g of copper, not more than 10 μg/g of boron, not more than 5 μg/g of lead and 8-12 μg/g of tin. The ratio between zinc, tin and copper elements in the metal silicon powder is 1:1-4:18-28. The average particle diameter of the metal silicon powder is 125 μm-180 μm. The specific surface area of the metal silicon powder is 0.6m2/g to 0.7m2/g. Compared with the prior art, the 100 mesh metal silicon powder has the following advantages and can greatly improve its ability to participate in chemical reactions and form products , the conversion rate of its metal silicon powder itself, the synthesis yield of the target product is as high as 90%, which is about 10% higher than that of ordinary metal silicon powder.
