Silicon (Silicium) is a chemical element in the
Cheap Replica Watches periodic table, its chemical symbol is Si, atomic number is 14. Silicon is a
Replica Watches tetravalent metalloid (tetravalent metalloid), the nature of carbon (Carbon) is similar, but more stable chemical properties of
rolex replica silicon. Silicon is mainly present in the rock, gravel, dust and so on. It can also be in silicate (including silicon, oxygen and other minerals) found, for example, feldspar (feldspar). Silicon is the main material of
Swiss Replica Watches the semiconductor device can be used in the manufacture of glass, ceramics, concrete and the like. Silicon is widely used as a semiconductor material, since germanium semiconductor is compared to the same (Germanium) higher temperatures, coupled with relatively easy to generate native oxide of silicon in a furnace tube, compared with most other materials, it is preferred semiconductors. Crystalline silicon is a dark gray, metallic shine like glass-like sheen, but harder than glass.
