The Use Of Silicon
① high purity monocrystalline silicon is an important semiconductor material. IIIA of the trace elements mixed in Mono, the formation of p-type Silicon semiconductor; addition of VA, trace elements, form n-type and p-type semiconductors together, you can make solar panels, radiant energy into electrical energy. In terms of energy is a promising material.
II important material of metal ceramics, Astronautical. Ceramic and metal sintering, made of metal-ceramic composite materials, high temperature resistant, resilient, can cut, inherited the merits of metals and ceramics, and made up for a combination of birth defects. Can be used in military weapons made the first space shuttle "Colombia" can withstand high speed through the dense atmosphere of friction heat, on which all the 31,000 pieces of Silicon building blocks of crust.
