Core Advantages of Green Silicon Carbide (SiC)
Green Silicon Carbide (SiC) is a high-performance synthetic abrasive and functional material, with key advantages in the following areas:

1. Exceptional Hardness & Wear Resistance
1.1 Mohs hardness of 9.2, second only to diamond and cubic boron nitride (CBN), making it ideal for processing ultra-hard materials (e.g., cemented carbide, ceramics, glass).
1.2 Superior abrasion resistance extends tool life in grinding, cutting, and polishing applications, outperforming conventional abrasives like white alumina.
2. Outstanding Thermal Stability
2.1Retains strength and hardness at extreme temperatures (up to 1600°C), suitable for high-speed grinding or high-temperature applications (e.g., aerospace component machining).
2.21High thermal conductivity reduces heat buildup, minimizing workpiece deformation.
3. Chemical Inertness & Corrosion Resistance
3.1 Resistant to acids and alkalis, ideal for corrosive environments (e.g., chemical processing, semiconductor manufacturing).
3.2 Non-reactive with metals, preventing contamination during machining.
4. Sharp Crystal Structure
Angular grains provide aggressive cutting edges, enabling precision machining (e.g., semiconductor wafer dicing, optical glass polishing).
5. Energy Efficiency & Environmental Benefits
5.1 Higher grinding efficiency reduces energy consumption compared to conventional abrasives (e.g., aluminum oxide).
5.2 Non-toxic material with recyclable waste, despite high-temperature production requirements.
6. Versatile Applications
6.1 Abrasive Processing: Hard metals (titanium alloys), ceramics, and composites.
6.2 Semiconductor & Electronics: Critical for wafer slicing and polishing (e.g., LED substrates).
6.3 Refractory Materials: High-temperature furnace linings and coatings.
6.4 Ballistic & Composites: Used in armor and lightweight structural reinforcements due to high hardness-to-weight ratio.
7. Electrical & Optical Properties
7.1 Acts as a semiconductor (when doped) for high-power, high-temperature electronics (e.g., power devices).
7.2 High infrared transmittance enables use in optical windows and laser components.
Comparison with Other Abrasives
vs. Black SiC: Green SiC has higher purity (≥99%) and hardness, preferred for precision work; black SiC is cost-effective for rough grinding (e.g., cast iron, stone).
vs. Diamond: More economical and better suited for non-ferrous metals (diamond reacts with iron-based materials).
Limitations
1. Brittle nature limits impact resistance, making it unsuitable for heavy-duty applications.
2. Higher production costs (due to pure raw materials and energy-intensive processes) compared to standard abrasives.
Conclusion
Green SiC’s unique combination of hardness, thermal stability, and chemical inertness makes it indispensable for high-precision and demanding machining tasks, particularly in advanced manufacturing and semiconductor industries.
