Product Description
What is Silicon Carbide?
Silicon carbide (SiC) is a high-performance ceramic compound synthesized from quartz sand and petroleum coke through high-temperature smelting. It combines exceptional hardness, high thermal conductivity, and remarkable chemical stability, making it indispensable across abrasives, refractories, metallurgy, and electronics.
Our silicon carbide is produced in China's premier manufacturing hubs with strict quality control. We offer both black silicon carbide (98%+ purity, cost-effective for industrial use) and green silicon carbide (99%+ purity, for advanced technical applications), with customizable particle sizes to meet your exact specifications.
