Specifications

Use:

1. Industrial silica fume widely used in refractories, powder metallurgy industry, to improve the product's high temperature, wear resistance and oxidation resistance. Its products are widely used in steel-making furnaces, kilns, kiln furniture.

2. in the organic silicon chemical industry, the industrial silicon powder is the basic raw material of the organic silicon polymer synthesis,, Waterproof and other characteristics.

3. the industrial silicon powder made by the single crystal silicon, processed silicon is widely used in high-tech fields, integrated circuits, electronic components essential raw materials.

4. Metallurgical casting industry, the industrial silicon powder as a non-iron-based additives, silicon steel alloy agent, thereby enhancing the steel hardenability. Industrial silicon powder can also be applied to certain metals reductant for new ceramic alloys.

5. for the production of silica sol.
