Applications of Green Silicon Carbide

• Photovoltaics: Wafer slicing slurry for silicon ingots
• Precision Lapping: Used in optical glass, ceramics, and semiconductors
• Refractories: High-temperature kiln linings and fire bricks
• Abrasives: Coated abrasives and bonded grinding wheels

Tips for International Buyers

• Request technical data sheets (TDS) and SDS
• Confirm compliance with REACH, RoHS (if exporting to EU)
• Negotiate trial orders for F1000–F2000 micro-powders
• Use FOB China or CIF quotations for transparency

FAQ

Q1: What is the difference between green and black silicon carbide?

A: Green SiC is purer and sharper, suitable for precision cutting and polishing. Black SiC is more durable but less pure, ideal for heavy-duty blasting and refractory uses.

Q2: Can green silicon carbide be used for solar wafer slicing?

A: Yes. GSiC with controlled particle size and high purity is widely used for slurry in photovoltaic ingot slicing.

Q3: Which grit size is suitable for lapping and polishing?

A: F800–F2000 or micronized GSiC powder is typically used for precision lapping and polishing operations.

Conclusion

As demand for advanced materials grows, green silicon carbide continues to play a critical role in high-tech and precision manufacturing. Whether you need GSiC for abrasives, ceramics, or solar applications, partnering with one of these top-tier manufacturers can help ensure consistent supply, technical support, and long-term value.
