Factory direct silicon metal powder 553# 3303# 2202# metallic silicon
Product Description
Silicon Metal Lump Properties
Our industrial silicon or silicon metal lumps come in irregularly shaped chunks. These chunks are silvery gray or dark grey with a metallic luster. These lumps are made up of quartz (SiO2) meaning they can be processed to extract high purity silicon. The material features a high fusing point, outstanding heat resistance, and high resistivity. The high purity silicon extracted from this product is a vital material in the production of electronics components.
Silicon Metal Lump Applications
The silicon metal lumps can be further processed into higher purity silicon and then used as an additive in aluminum alloy ingot smelting, steel production, aluminum alloy production, and electronic component production.
