Silicon Kr0

Designation

Name The value
Designation GOST Cyrillic Кр0
Designation GOST Latin Kp0
Transliteration Kr0
The chemical elements C0

Description

Silicon Kr0 is used: for the manufacture of silicon alloys, silicone products, silicon semiconductor, and also for sparcely.

Note

Silicon Kr0 is produced by reduction smelting of the quartzite in the electric arc furnace.

Standards

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

Chemical composition

Standard Si Fe Al Ca
GOST 2169-69 ≥98.8 ≤0.5 ≤0.4 ≤0.4
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%.
