Are metal silica powder and silica powder the same product?

What's the difference between metal silica powder and silica powder?

First of all, metal silicon powder and silicon powder are not the same product, the two have essential differences.  

Introduction to metal silicon powder

Silicon metal (industrial silicon) after grinding and processing of powder silicon powder.

Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys.  Industrial silicon is also used as an alloying agent for demanding silicon steel, smelting special steel and deoxidizer for non-iron based alloys.  Industrial silicon can be drawn into monocrystalline silicon after a series of processes for use in electronics industry.  

The use of metal silicon powder:

1. Metal silicon powder is widely used in refractory materials, powder metallurgy industry, in order to improve the product's high temperature resistance, wear resistance and oxidation resistance.  Its products are widely used in steelmaking furnaces, kilns and kiln tools.  

2. In the organic silicon chemical industry, metal silicon powder is the basic raw material for the synthesis of organic silicon polymer, such as used for the production of silicon monomer, silicone oil, silicone rubber preservatives, so as to improve the product's high temperature resistance, electrical insulation, corrosion resistance, corrosion resistance, waterproof and other characteristics.  

3. Metal silicon powder by drawing made of monocrystalline silicon, processed silicon wafers are widely used in the field of high-tech, integrated circuits, electronic components essential raw materials.  

4. Metallurgical casting industry, metal silicon powder as non-ferrous alloy additives, silicon steel alloy agent, so as to improve the hardenability of steel.  Industrial silicon powder can also be used in some metal reducing agent, used in new ceramic alloys, etc.  

Introduction to silicon powder  

Silicon powder silicon powder, also known as silica ash, is silicon metal or ferroalloy in the production process, is recycled smoke, because the silica powder contains is very high, and the particles are very fine, it is not only in rubber, paint industry, in concrete and so on is also widely used in the industry!  Silica powder has volcanic activity.  

The use of silicon powder:

1. Control concrete material segregation and bleeding, reduce or avoid concrete honeycomb, pockmarked, weak interlayer, cracks and milk skin defects.  

2. Improve the compressive strength of concrete, the test proves that silicon powder can greatly improve the strength of concrete.  

3. Improve the durability of concrete, improve the permeability of concrete, frost resistance, wear resistance and corrosion resistance.

4. Improve the carbonization resistance of concrete, for reinforced concrete, the incorporation of silicon powder injustice can improve the bond strength between the matrix and the steel bar, but also enhance the corrosion resistance of steel bar.  

5. Improve the fluidity and density of refractory materials, improve the high temperature strength and thermal shock of refractory materials.
