Silicon Metal 2202 Rare Metals

Silica rock is used as raw material for chemical silicon metal production and low ash carbon material as reducing agent. The main raw materials for producing chemical silicon by electric furnace are silica and carbon. Carbon raw materials are mainly petroleum coke, high-quality anthracite or charcoal, can also be mixed with a part to increase the charge ratio resistance.

Description

Description

Silicon metal is a gray and shiny semiconductor metal,also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys which smelted from quartz and coke in an electric furnace. They are rare metals, non-ferrous metals, coal and building materials.It is widely used in semiconductor, solar energy, synthetic metal and other materials. Industrial silicon is in great demand. We can provide silicon and aluminum alloy for concrete, fireproof materials and hard glass processing.
