Silicon Metal Silicon is a lustrous black solid that looks like a metal, and it is sold commercially as "Silicon Metal". Silicon is used when alloyed with various metals. Silicon metal 98 generally refers to metal silicon with a silicon purity of 98% and above. Like other types of silicon metal, it is smelted from silica and coke through deoxidation and reduction. But it is an industrial silicon metal product that does not reach the regular standard. General silicon metal refers to metal silicon with a purity of 98.5% and above. For example, silicon metal 553, its purity can reach 98.5%, so it is also called silicon metal 98.5. Silicon Metal lump was produced in electric heating furnace by quartz and coke. Quartz will be redox and became molten silicon liquid. After cooling, it will be solid as we see. The primal silicon metal lump is very large. Then it will be made into smaller lumps which we call standard size. Silicon Metal Lumps will be 10-100mm.

High quality 2. Competitive price 3.Prompt delivery Prompt delivery Usage锛?/strong> 1. Silicon metal can be used to make silicon crystals,silicone rubber,silicone oil etc. 2. Silicon metal can be used in the aluminum alloy industry. 3. Silicon metal can also be used as the basic raw material in the chemical industry. 4. Silicon metal can make high purity semiconductor. 5. Automobile industries employ aluminum that requires a quite large industrial silicon,so the country's auto industry development has a direct effect on industrial silicon market. 6. Silicon metal can replace pure aluminium in steelmaking. Silicon Metal website:http://www.zhongxing-silicon.com/silicon-metal/
