DESCRIPTION
“silicon metal” (also known as industrial silicon in my country) is a commodity name that appeared in the mid-1960s. Its appearance is related to the rise of the semiconductor industry. The international practice is to divide commercial silicon into metal silicon and semiconductor silicon. Silicon metal is a product smelted from quartz and coke in an electric furnace. The main component silicon content is about 98% (99.99% of Si content is also included in metal silicon), and the remaining impurities are iron, aluminum, calcium, etc.
