Silicon Metal Powder

Metallurgical Material

Description

Silicon Metal, also named crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. It is a product made by smelting quartz and coke in an electric furnace. The main element silicon content is about 98%, and the remaining impurities are iron, aluminum, Calcium, etc. Silicon metal is hard and brittle. It is insoluble in acid at room temperature and easily soluble in alkali.
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.

Advantages:

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.
