Silicon Kr3

Designation

Name The value
Designation GOST Cyrillic Кр3
Designation GOST Latin Kp3
Transliteration Kr3
The chemical elements C3

Description

Silicon Kr3 is used: for the manufacture of silicon alloys, silicone products, silicon semiconductor, and also for sparcely.

Note

Kr3 silicon 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 ≥96 ≤1.5 ≤1.5 ≤1.5
Si is the basis.
According to GOST 2169-69 the sum of detectable impurities is ≤ 4.00%. 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: Kp3A 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.
