Standards

Name Code Standards
Non-ferrous metals, including rare, and their alloys В51 GOST 2169-69

Chemical composition

Standard Si Fe Al Ca
GOST 2169-69 ≥97 ≤1 ≤1.2 ≤0.8
Si is the basis.
According to GOST 2169-69 the sum of detectable impurities is ≤ 3.00%. 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: Kp2A 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.
