DESCRIPTION
China Silicon metal 553 is a high-purity grade of silicon metal that typically contains over 99.5% silicon. It is produced by reducing silica (SiO2) with carbon in an electric arc furnace at high temperatures. The resulting silicon metal is then refined to remove impurities and improve its purity.
China Silicon metal 553 is widely used in the production of various silicon-based products, including semiconductors, solar cells, and electronic components. It is also used as an alloying agent in the production of aluminum and steel, as well as in the production of silicone polymers and other high-performance materials.
The number “553” in the name of the material refers to its typical composition. Specifically, it contains 5% or less of aluminum (Al), 5% or less of calcium (Ca), and 3% or less of iron (Fe). The remaining percentage is mostly silicon (Si), with trace amounts of other elements.
