What are silicon and silicon dioxide often used for?
Pure silicon industry called metal silicon as a semiconductor wafer, solar wafer, industrial raw materials for the production of trichlorosilane silicon is the basic material of organic silicon industry.
Silica natural form is called quartz, it is crystal form, industrial use mostly from silicon ore industrial purification, can make all kinds of quartz products, such as crystal cup, crystal bowl, music buckle of advanced products.
You can also make the quartz crystal jewelry, such as SWAROVSKI; there is another form of silica, amorphous silica, which is a very fine powder and carbon black, because similar effects, color is white, the industry called silica as reinforcing material. The chemical is also used as a chromatographic stationary phase with a certain particle size of silica.
