What are the characteristics of silicon crystal and where are its main applications?

Silicon crystal is dark blue and fragile, which is a typical semiconductor. The chemical properties are very stable. It is difficult to react with substances other than hydrogen fluoride at room temperature. Heteromorphic silicon includes amorphous silicon and crystalline silicon. Application: Silicon is a semiconductor material, which can be used to make semiconductor devices and integrated circuits. It can also be used in automobile and mechanical parts in the form of alloy (such as ferrosilicon alloy). It is also used in cermets of ceramic materials. It can also be used to make glass, concrete, bricks, refractories, siloxanes and silanes.
