Usage
1. Silicon metal is widely used in smelting alloy elements, as a reducing agent in many kinds of metal smelting.2.Silicon metal 441 is widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.3.Silicon metal 441 is regarded as alloy additive, improve the steel hardenability in metallurgy and foundry industry.4. Silicon metal 441 which is sublimated into monocrystalline silicon, which is widely used in highttech field as essential raw material for integrated circuit and electronic element. 5.Metalic silicon 441 are used in high-temperature material production in order to manufacture enamels and pottery.These also cater the demands of semiconductor industry by producing ultra-pure silicon wafers
