Green Silicon Carbide (Carborundum )

Green Silicon Carbide (SiC) – The High-Performance Abrasive for Precision Applications

Green silicon carbide is an advanced synthetic abrasive material produced through an electric resistance furnace process at extreme temperatures exceeding 2200°C. While its manufacturing method shares similarities with black silicon carbide, green SiC demands higher-purity raw materials-primarily petroleum coke and high-grade quartz sand, with salt added as a reaction accelerator. The result is a distinct green-hued, hexagonal crystalline structure with exceptional hardness, ranking just below diamond and surpassing corundum in cutting performance.

Key Characteristics & Advantages

Superior Hardness & Sharpness – Ideal for precision grinding, lapping, and polishing of hard, brittle materials.

High Thermal & Electrical Conductivity – Enhances heat dissipation in high-speed applications and exhibits semiconductor properties.

Controlled Brittleness – More friable than black SiC, ensuring continuous self-sharpening during grinding for consistent surface finishes.

Exceptional Purity (≥99% SiC) – Minimizes contamination, making it suitable for semiconductor and optical applications.

Manufacturing & Processing

Green silicon carbide blocks are crushed, milled, and precisely classified through advanced processes such as vertical ball milling, acid washing, hydraulic grading, and ultrasonic sieving. This ensures:

Uniform Particle Distribution – Tightly controlled grain sizes eliminate coarse or overly fine particles.

High Surface Cleanliness – Acid washing removes impurities, enhancing abrasive performance.

Optimized Geometry – Engineered for maximum cutting efficiency and minimal workpiece scratching.

Product Classification & Applications

Green SiC is categorized based on production methods and end-use requirements:

P-Grade (Coated Abrasives)

Produced via crusher processing for sharp, aggressive cutting.

Used in abrasive belts, sandpaper, and emery cloth for metal, wood, and composite finishing.

F-Grade (Bonded Abrasives)

Processed via ball milling for dense, high-strength grains.

Ideal for ceramic/resin grinding wheels, honing stones, and cutting tools.

W-Grade (Micro Powders)

Ultra-fine powders (sub-micron to single-digit microns) produced through jet milling and air classification.

Applied in precision polishing slurries, specialty coatings, and advanced ceramics.

Industry Applications

Semiconductor & Optics – Lapping silicon wafers, sapphire, quartz, and LED substrates.

Advanced Ceramics – Additive for high-strength refractory materials.

Aerospace & Automotive – Finishing turbine blades, bearings, and high-tolerance components.

Surface Treatment – Delivering mirror finishes on metals, glass, and composites.
