Silicon is the second most abundant element in the earth's crust (behind only oxygen) and the eighth most common element in the universe.
Silicones Production. The silicone manufacturing process sounds simple. Take silicon, methyl chloride, and a dash of catalyst. Heat. Add water. And out pops an infinite assortment of silicone fluids, elastomers, gels, and resins.Silicon Metal The Quartz Corp High Purity Quartz,Silicon Metal All silicon metal shares a common origin: Quartz (SiO2). Quartz is reduced to silicon (Si) in a high temperature melting process using carbon and high temperatures in an electric arc furnace.
Silicon Metal Manufacturing. Silicon metal is produced in a number of complex and highly technical steps. First, the raw materials (quartz sand and charcoal) are placed in an electric arc furnace and heated to 2,000°-2,500°C.Silicon Metal CRM Alliance Critical Raw Materials,Silicon metal is commonly produced by smelting submerged electric arc furnaces, which is an energy-intensive process. Further processing of the material into different product grades makes it applicable in many industry processes.
The metal is then cast, cooled and adapted according to the refining, granulometric and packaging specifications required by the customer. In our daily lives, Silicon is the raw material for the following applications: Silicones and silanes used for their waterproofness, for glues and mastics' adhesion, for their insulating properties and for moulds' production.Silicon Metal, Manganese Metal,Silicon Metal ,Si 97 is a metallurgical grade silicon metal, it is an ideal substitute of silicon metal 553. It has good performance in aluminum industry, solar panels manufacturing, silicon based polymers product, semi-conductor grade silicon, iron base alloy production and so on.
