Metall kremniydan 200 so'm
Metall kremniyning 200 so'mining tasnifi odatda temir, alyuminiy va kaltsiyning metall kremniy tarkibida joylashgan uchta asosiy ta'sirchanlikning mazmuniga asoslanadi. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101, etc.
Sanoatda metall kremniy odatda elektr tokida uglerodli silikon dioksidni kamaytirish orqali amalga oshiriladi. Chemical reaction equation: SiO2+2C→Si+2CO The purity of silicon obtained in this way is 97~98%, which is called metal silicon. U eritilgan va kristalatsiyalangan va iflosliklar metall kremniyni 99 ga olish uchun olib tashlanadi. 7-99. 8%.
