What is Silicon Metal Powder?

Silicon metal powder is a finely ground form of metallic silicon, which typically has a silicon content of 98% or higher. It is produced by crushing and grinding silicon metal into smaller particles to meet specific size requirements for different industrial applications. Silicon metal is usually derived from quartz (silica) in submerged electric arc furnaces and refined for purity.

Properties of Silicon Metal Powder

• High Silicon Content: Generally ranges between 98% and 99.9%.
• High Purity: Low levels of impurities like iron, aluminum, and calcium.
• Thermal Stability: Resistant to high temperatures.
• Chemical Inertness: Resistant to most chemical reactions.
• Good Conductivity: Offers high thermal and electrical conductivity.
