  • List of silicon producers Wikipedia

    This is a list of silicon producers.The industry involves several very different stages of production. Production starts at silicon metal, which is the material used to gain high purity silicon.High purity silicon in different grades of purity is used for growing silicon ingots, which are sliced to wafers in a process called wafering.Silica Department of Mines, Industry Regulation and Safety,Silica can be identified by considering the types of materials used in the task. More information is available in material safety data sheets where these are available (eg for abrasive blasting agents) and from material suppliers. The risk of silica exposure from the task is assessed by examining the work processes involving crystalline silica.
