Metallurgical Grade Refractory Silicon Carbide/Sic Powder/Lump 88 90
Metallurgical Grade Refractory Silicon Carbide (SiC), available in both powder and lump forms with purity levels of 88% and 90%, is a high-performance material designed for metallurgical, refractory, and abrasive applications. Produced through the carbothermic reduction of silica sand and carbon in electric arc furnaces, this SiC variant offers a balance of cost-efficiency and functional performance, making it suitable for industrial-scale operations.
The 88% and 90% purity levels ensure adequate performance in applications such as deoxidation, slag conditioning, and metal refining, where extreme purity is not mandatory but thermal and mechanical resilience is essential. In powder form, it is used as an additive in refractory mixes, improving thermal stability and durability in high-temperature environments such as furnace linings and kilns. The lump form is ideal for manufacturing refractory bricks, kiln furniture, and abrasives, where structural integrity and thermal shock resistance are critical. This grade of SiC exhibits high thermal conductivity, hardness, and chemical inertness, allowing it to withstand extreme environments without degradation.
Commonly used in steelmaking, iron casting, and non-ferrous metal production, Metallurgical Grade SiC helps improve metal quality and process efficiency. Its availability in both powder and lump forms provides flexibility for diverse industrial applications. Whether used for refractory construction, abrasives, or metallurgical additives, 88%–90% Pure Silicon Carbide is a reliable, cost-effective solution for high-temperature and heavy-duty industrial processes.
