"Metal Silicon" (also known as industrial silicon in China) is a commodity name appearing in the mid-60. Its emergence is related to the emergence of the semiconductor industry. International common practice is to divide commodity silicon into metal silicon and semiconductor silicon. Metal silicon is made from quartz and coke in the electric furnace smelting products, the main components of silicon content in about 98%% (including Si 99.99% in the silicon also included in the metal), the rest of the impurities for iron, aluminum, calcium and so on. Semiconductor silicon is used to fabricate high-purity silicon metal for semiconductor devices. is a polycrystalline, single crystal form of sale, the former cheap, the latter price ang. It is classified as a variety of specifications for different purposes. According to statistics, 1985 the world's total consumption of metal silicon about 500,000 tons, which is used for aluminum alloy metal silicon accounted for about 60%, for the organic silicon less than 30%, for the semiconductor accounted for about 3%, the rest of the steel smelting and precision ceramics.
