The Properties and Uses of Silicon Metal
Silicon metal is a grey and lustrous semi-conductive metal that is used to manufacture steel, solar cells, and microchips. Silicon is the second most abundant element in the earth's crust (behind only oxygen) and the eighth-most common element in the universe. Nearly 30 percent of the weight of the earth's crust can be attributed to silicon.
