Green Silicon Carbide (GC) is a high-purity variant of silicon carbide, typically synthesized from quartz sand and petroleum coke in resistance furnaces at temperatures exceeding 2200°C. With SiC content over 99%, it features translucent green crystals, Mohs hardness of 9.2-9.5, and microhardness of 3100-3400kg/mm². GC exhibits exceptional hardness, high brittleness, superior thermal conductivity, and strong chemical inertness. Compared to black SiC, GC offers higher purity and sharper grains but slightly lower toughness, making it ideal for processing ultra-hard materials.

Key applications include:

• Precision Grinding: Fine machining of cemented carbide, titanium alloys, optical glass, and ceramics
• Polishing: Ultra-smooth surface treatment for semiconductor wafers, gemstones, and quartz devices
• Advanced Refractories: High-performance kiln furniture, nozzles, and specialty ceramics
• Electronics: As semiconductor substrates or thermal conductive fillers

Owing to its outstanding cutting performance and chemical stability, GC is widely used in high-tech industries like precision machinery, optoelectronics, and aerospace, serving as an indispensable abrasive for advanced manufacturing.
