Green Silicon Carbide (SiC) is a prized industrial material known for its extraordinary hardness, thermal stability, and chemical resistance. With Vietnam's accelerating growth in advanced manufacturing and export-oriented industries, the country has become a strategic hub for producing Green Silicon Carbide. This article provides a comprehensive overview of the Top Green Silicon Carbide manufacturers and suppliers in Vietnam, highlighting its manufacturing processes, technological innovations, market dynamics, and the most competitive suppliers serving the global abrasive, refractory, and semiconductor fields.
Green Silicon Carbide is synthetically produced through the high-temperature reaction of quartz sand (silica) and petroleum coke in resistance furnaces—often with salt as a catalyst. The process yields crystalline silicon carbide, exhibiting a green hue due to its high purity and specific crystal structure.
- Hardness: Green Silicon Carbide ranks immediately below diamond on the Mohs scale, making it ideal for precision grinding and cutting.

Vietnamese manufacturers mostly rely on the Acheson process—an enduring technique since the 19th century—with advances in furnace design and purification. The process proceeds as follows:[1][5][7]
1. Raw Material Selection: High-purity quartz sand and low-ash petroleum coke are prepared, sometimes with salt as a flux to improve yield.
2. Carbothermal Reduction: These materials are mixed and loaded into electric resistance furnaces, then heated to about 2200°C. The reaction forms SiC crystals, releasing waste gases and forming ingots.
3. Cooling and Extraction: Upon cooling, silicon carbide ingots are extracted, with excess free carbon and silicon separated.
4. Purification: Pickling and chemical leaching are applied to remove impurities, followed by mechanical crushing.
5. Classification: The crushed SiC is sieved, milled, and classified into microgrits or powders of defined size ranges.
6. Quality Assurance: Particle size distribution, purity, and hardness tests are conducted per FEPA/JIS standards and ISO certifications.
Newer processes being piloted in Vietnam include the use of recycled silicon waste and methane/biogas to lower environmental impact and production costs. Controlled atmosphere furnaces and smart manufacturing systems reduce toxic emissions and enhance yield, positioning Vietnam favorably in the shift toward greener silicon carbide technologies.[5][2]
