silicon dross powder

Silicon powder,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. 

Silicon Powder Used in Other Industries

 

1.In chemical industry,Silicon powder is used for producing silicone monomer,silicone oil, Silicone rubber preservative,Silica sol.

 

2.In high-tech area,Silicon powder is used for making integrated circuit and electronic components.

 

3.In metallurgy casting industries,Silicon powder is used as non-ferrous alloys additive, Silicon steel alloy agent.

 

4.In solar industry,Silicon powder also can be used for making polysilicon.
