High Purity Green Silicon Carbide Powder for Precision Grinding and Polishing

High Purity Green Silicon Carbide Powder for Precision Grinding and Polishing

Product Description:

Green silicon carbide powder is a type of silcon carbide product that has high thermal conductivity and high strength at elevated temperatures. It is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace. The result of this high-temperature process is the crystalline form of silicon carbide grains, of both Green and Black coloring. The color difference is due to the purity of the silicon carbide. Green SiC is of higher purity than black silicon carbide. Green silicon carbide is produced in the same way as black silicon carbide, but with different requirements for raw materials. Green silicon carbide is made of petroleum coke and high-quality silica as the main raw material. It is added with salt as an additive and is smelted by high-temperature resistance furnace. The mark of green silicon carbide is usually GC, the crystallization is α-SiC, with hexagonal or rhombohedral crystal type, containing SiC around 99%.

Green Silicon Carbide Abrasives Applications:

Grinding and Polishing: Ideal for fine grinding and polishing of materials like ceramics, glass, and gemstones.
Refractory Materials: Used in the production of high-temperature-resistant products like bricks, tiles, and kiln linings.
Abrasive Tools: Often used in the production of cutting discs, grinding wheels, and sandpaper.
Semiconductor Manufacturing: Due to its excellent electrical conductivity and hardness, it is used in semiconductor applications.
Blasting Media: Utilized in sandblasting for cleaning and surface finishing due to its sharp cutting edges.

Green Silicon Carbide Abrasives Technical Specifications

Q&A:

Q: What is green silicon carbide used for?

A: Green Silicon Carbide is mainly used for precision grinding, cutting, polishing, ceramic manufacturing, refractory materials, semiconductor wafer processing, and abrasive tools.
Its high purity and sharp cutting ability make it suitable for high-end and precision applications.

Q: How is Green Silicon Carbide different from other abrasives like Aluminum Oxide? 

A: Green Silicon Carbide is harder and sharper than aluminum oxide, making it ideal for fine grinding and precision work. It also has a higher thermal conductivity, which makes it well-suited for high-temperature environments.

Q:What is the difference between 3C SiC and 4H SiC?

A: 3C-SiC is suitable for high-frequency and high-power devices due to its high saturated electron drift speed. 4H-SiC has become an ideal choice for power electronic devices due to its high electron mobility, low on-resistance and high current density.
