Technical Description and Industrial Uses of Refined Si Metal Powder
Refined Industrial Si Metal Powder 99.8% is a precision-engineered material produced through vacuum refining, fine grinding, and controlled magnetic separation. It exhibits high stability, smooth dispersion, and low oxidation during high-temperature operations, ensuring clean and efficient metallurgical reactions.
This powder is widely used in metal alloy refining, silicone compound manufacturing, and ceramic composite production. Its uniform granularity improves reaction uniformity, product brightness, and chemical bonding strength. Each batch is tested for particle distribution, chemical balance, and moisture control to meet international export standards.
