Silicon Metal

Product description

Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Industrial silicon is also used as an alloying agent for strict silicon steel, a deoxidizer for smelting special steel grades and non-ferrous alloys.

Performance and Features

1. The classification of metal silicon is usually based on the content of the three main impurities of iron, aluminum and calcium contained in the metal silicon component.

2. The metal silicon component is mainly silicon, so it has similar properties to silicon. Metal silicon has properties similar to germanium, lead, and tin, it has semiconductor properties.

Applications

Metal silicon should be used to produce organic silicon, produce high-purity semiconductor materials, and formulate alloys for special purposes.
