Green Silicon Carbide Polishing Powder

Green Silicon Carbide is produced in a high-temperature resistance furnace using petroleum coke and high-purity silica as the main raw materials, with salt added as a reaction promoter. The resulting crystal is characterized by high purity and significant hardness-positioned between corundum and diamond-and possesses mechanical strength exceeding that of corundum.

Coded as GC, Green Silicon Carbide is suitable not only for processing hard alloys, glass, ceramics, and non-metallic materials, but is also widely used in semiconductor manufacturing, high-temperature silicon carbide heating elements, and as a substrate material for far-infrared emitters.

Manufacturing of Polishing Powder

The polishing powder is obtained by crushing large green silicon carbide crystals, reshaping the grains in a vertical ball mill, followed by pickling, hydraulic grading, and natural sedimentation before final drying. This process yields a product with stable quality, excellent crystallinity, and high surface purity. The powder is free of oversized particles, contains minimal fines, and features a concentrated grain‑size distribution. These characteristics make it particularly suitable for precision grinding and polishing applications, delivering uniform workpiece finishes without surface scratches.

Applications

Green silicon carbide polishing powder is widely used across multiple high‑precision industries, including:

Production of precision grinding stones and bonded abrasive tools

Surface grinding and polishing of semiconductors, silicon wafers, quartz, sapphire, and other optical‑electronic components

Additive material in advanced ceramics and high‑performance refractories

Classification by Process and Use

In the abrasive industry, green silicon carbide is categorized according to production method and end‑use:

P‑Series (Crushed Grain)​ – Produced via crusher systems, these grains are sharp and offer good self‑sharpening properties. Primarily used in coated abrasives such as abrasive belts, cloths, and sandpaper.

F‑Series (Milled Grain)​ – Typically milled in ball mills or Barmac‑type equipment, resulting in high packing density and strength. Mainly employed in consolidated abrasives like ceramic grinding wheels, grinding blocks, and resin‑bonded wheels.

W‑Series (Ultrafine Powder)​ – Produced through deep processing of raw blocks using Barmac crushers, Raymond mills, or ball mills, followed by ultrasonic classification. This ultrafine powder is used in specialized applications such as coatings and sealing compounds.
