DESCRIPTION
silicon metal (silicon content is mainly 98.5%), originally mainly metallurgical silicon, chemical silicon (silicon content is mainly 99.85%). The classification of silicon metal is usually based on the content of iron, aluminum, calcium three main impurities contained in the silicon metal composition. According to the content of ferro, aluminium and calcium in silicon metal, silicon metal can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.
