Product Description

Metallurgy First Choice! 553 Metallic Silicon, High Strength, Low Impurities, Cost Straight Down 30%
 

Product Description

 

The preparation of metallic silicon usually uses silica as the raw material. The formation of silicon metal is a complex process involving chemical reaction, high temperature melting, refining and purification. By precisely controlling the reaction conditions and parameters, high quality metallic silicon products can be obtained. The appearance of metallic silicon is grayish brown with metallic luster, hard and brittle silicon blocks, with good electrical conductivity and semiconductor properties.
