Advanced metal silicon generation background

Date: 04-15-2021
 Silicon metal is an important raw material for the stainless steel industry and aluminum alloy industry. High quality silicon metal raw materials are crucial for the production of stainless steel and aluminum alloy.Therefore, these manufacturers tend to purchase silicon metal when the use of advanced silicon metal raw materials.

Advanced silicon metal is a commodity name that appeared in the middle of the 1960s.Its emergence is related to the rise of the semiconductor industry.The international common practice is to divide commercial silicon into metal silicon and semiconductor silicon.Silicon metal is a product smelted by quartz and coke in an electric furnace. The content of silicon element in the main component is about 98% (Si content of 99.99% is also included in the silicon metal), and the other impurities are iron, aluminum, calcium and so on.A high purity silicon metal used to make semiconductor devices.It is polycrystalline, single crystal form sold, the former is cheap, the latter is expensive.Because of its different uses and divided into a variety of specifications.According to statistics, in 1985, the whole world consumed about 500 thousand tons of silicon metal, of which the silicon metal used for aluminum alloy accounted for about 60%, used for organic silicon less than 30%, used for semiconductor accounted for about 3%, the rest for iron and steel smelting and precision ceramics.
