Si is the basis.
According to GOST 2169-69 the sum of detectable impurities is ≤ 1.20%. In silicon intended for the production of aluminum-silicon alloys, the mass fraction of aluminum is allowed up to 2.0% with a corresponding decrease in the mass fraction of silicon. In this case, the letter A: Kp0A is added to the designation of the brand of silicon. In silicon intended for the chemical industry, the mass fraction of titanium should not exceed 0.2% with a corresponding decrease in the mass fraction of silicon. According to the manufacturer's agreement with the consumer for silicon semiconductor production, as well as for special purposes, silicon grade Kr0 with a mass fraction of aluminum does not exceed 0.3%.
