Applications of Silicon Silicon is one of man’s most useful elements. In the form of sand and clay it is used to make concrete and brick; it is a useful refractory material for high-temperature work‚ and in the form of silicates it is used in making enamels‚ pottery‚ etc. Silica‚ as sand‚ is a principal ingredient of glass‚ one of the most inexpensive of materials with excellent mechanical‚ optical‚ thermal and electrical properties. Hyperpure silicon can be doped with boron‚ gallium‚ phosphorus
