4 Silicon carbide (SiC) specifications

1. Common Grades of Silicon Carbide

? Metallurgical Grade (60-95% SiC) – Used as a deoxidizer and carbon enhancer in steelmaking and foundries. ? Abrasive Grade (95-99% SiC) – Used for grinding wheels, sandblasting, and cutting applications. ? Refractory Grade (90-99% SiC) – Used in high-temperature furnaces and kiln linings. ? Electronic Grade (99.9%+ SiC) – Used in semiconductors, power electronics, and LED manufacturing.

2. Chemical Composition of Different Grades

3. Particle Size Distribution

?? Lumps: 10-50mm, 1-10mm (Used in steelmaking, foundries)

?? Granules: 0.2-1mm, 1-3mm, 3-5mm (Used for abrasives, refractories)

?? Powder: 200-400 mesh (Used in polishing, ceramics, and coatings)

4. Silicon Carbide Applications Based on Grade

• Metallurgical Grade SiC (88-90%): Steelmaking deoxidizer, foundry additives, smelting
• Refractory Grade SiC (98-99%): High-temperature kiln linings, crucibles, burner nozzles
• Abrasive Grade SiC (98-99.5%): Grinding wheels, cutting tools, sandblasting
• Electronic Grade SiC (99.9%+): Semiconductor wafers, LEDs, power electronics
