1. Overview of Silicon Carbide Industry in China

China dominates the global silicon carbide (SiC) production landscape, accounting for more than 60% of worldwide supply. With abundant quartz sand, petroleum coke, and advanced electrofusion technology, Chinese manufacturers have built complete production chains for both black SiC (carbon-rich type) and green SiC (high-purity type). The industry is centered in Henan, Shandong, and Ningxia provinces — known for reliable industrial clusters and established logistics networks for global shipping.

In recent years, China’s SiC industry has diversified beyond traditional abrasives into advanced materials for semiconductors, ceramics, and high-temperature refractories. The integration of refining, crushing, classification, and FEPA/JIS standard processing ensures consistent quality for global buyers.

2. Types and Grades of Silicon Carbide

Chinese suppliers typically provide multiple types and grades of SiC to meet different industrial needs:

Black Silicon Carbide (SiC 97–99%) – Ideal for grinding wheels, blasting media, refractory bricks, and metallurgical additives.
Green Silicon Carbide (SiC 99% up to 99.9%) – High-purity and sharper; widely used in precision lapping, polishing, and semiconductor wafer processing.
Metallurgical Grade SiC (SiC 88–95%) – Applied in steelmaking and foundry industries as a deoxidizer and carbon additive.
Micro Powder (D20–D10000) – Ultra-fine SiC powder for polishing compounds, ceramics, and coating materials.

Most manufacturers follow FEPA (Europe), JIS (Japan), and ANSI (US) grit standards to ensure compatibility with international specifications.
