553 Silicon Metal

Silicon metal is a high-purity form of silicon, primarily produced by reducing quartz (SiO₂) with carbon in an electric arc furnace at high temperatures (~1,800°C). The result is a metallic, crystalline silicon with purity levels typically ranging from 98% to 99.99%.

High Purity – Typically 98-99.99% Si, with impurities like iron, aluminum, and calcium.
High Melting Point – 1,414°C, making it heat-resistant.
Brittle and Crystalline – Breaks easily into shiny, gray metallic chunks.
High Conductivity – Used in semiconductors and electronics.
