Silicon Powder - 99% Min Purity, -20 To -325 Mesh Sizes | High Melting Point, Superior Heat Resistance, Cost-effective Refractory Material

We are engaged in manufacturing, exporting and supplying excellent quality Silicon Powder to our valuable clients. It is silver gray or dark gray powder with metallic luster. With the characteristic of high melting point, good heat resistance, high resistivity and high antioxidant effect, it is the basic raw material to refractiry industry,such as refractory castables,stopper rod.

Applications
1.Substitute for Aluminum oxide mud as refractory material.
2.Used as additive in producing amorphous and shaped refractory products, greatly improve the strength and high-temperature behavior.
3.Used as castables binder of teeming ladle.
4.As cohesive agent, binder, coagulant, additives of other refractory products.

Advantage
1.Substitute for traditional Silicon metal powder as refractory material, reduce product cost.

2.Size distribution is more uniform.

3.Stable performance and prolong the service life of refractory products.
