Factory Supply Silicon Metal Lump 421 And 441 Silicon Slag

Factory Supply Silicon Metal Lump 421 and 441 Silicon Slag is not easily melted or decomposed at conventional industrial smelting temperatures (1000-1600°C). Instead, it forms a stable SiO₂ oxide film (melting point 1723°C) that covers the material surface, insulating it from air and melt corrosion. Therefore, it is suitable for high-temperature environments (e.g., furnace linings and alloy smelting).
