Green Silicon Carbide 400#600#800#1000#Silicon Carbide Powder

Green Silicon Carbide (SiC) is a high-purity, synthetic abrasive material produced in an electric resistance furnace using silica sand and petroleum coke as raw materials, with the addition of salt. It is a harder and more brittle variant compared to black silicon carbide.

Key Properties:

• Hardness: ~9.5 on the Mohs scale (harder than black SiC and aluminum oxide)

• Purity: Higher than black SiC (≥97% SiC)

• Crystal Structure: Sharp, angular grains

• Thermal Conductivity: High

• Chemical Resistance: Excellent against acids and alkalis

• Fracture Toughness: Lower than black SiC, making it sharper but more brittle

Applications:

1. Abrasive Tools:

   • Used in grinding wheels, sandpaper, and abrasive blasting for hard materials like carbide, ceramics, and glass.

2. Lapping & Polishing:

   • Ideal for precision finishing of tungsten carbide, titanium, and optical lenses.

3. Refractory Materials:

   • Added to high-performance refractories for improved thermal shock resistance.

4. Semiconductor & Electronics:

   • Used in wafer grinding and as a substrate material for high-power electronics.

5. Wire Sawing:

   • Employed in cutting silicon wafers and photovoltaic cells.

6. Anti-Slip & Coatings:

   • Added to paints and coatings for slip resistance.

Advantages Over Black Silicon Carbide:

• Higher purity and sharper grains → better cutting performance.

• More efficient for precision grinding of hard, brittle materials.

• Less iron contamination, making it suitable for semiconductor applications.

Disadvantages:

• More expensive than black SiC due to higher purity requirements.

• More brittle, leading to faster wear in some applications.
