DESCRIPTION
Silicon metal powder is produced by reducing high-purity silica with carbon in an electric furnace at high temperatures. The resulting silicon metal is then crushed into fine powder, which can be used in various applications such as the production of alloys, ceramics, and electronic components.
The properties of silicon metal powder depend on various factors such as the particle size, purity, and morphology. For example, small particle size and high purity are desirable in some applications such as the production of solar cells, while larger particle size and lower purity may be acceptable in other applications such as the production of silicon alloys.
Storage:
- Silicon metal powder is a hazardous material that should be handled with care.
- Store in a cool, dry, well-ventilated area away from heat sources and oxidizing agents.
- Use appropriate personal protective equipment, including gloves, safety glasses, and a respirator.
- Avoid contact with skin, eyes, and clothing.
- Do not ingest or inhale the powder.
- Follow all safety guidelines and regulations for handling hazardous materials.
