Green Silicon Carbide

Green silicon carbide is made by melting siliceous quartz sand and petroleum coke at high temperature in an electric arc furnace. Green silicon carbide particles are sharp and blocky, high purity, extremely high hardness (Mohs hardness 9.4 / Knoop hardness 2600), strong cutting force, stable chemical properties, good thermal conductivity, and high high temperature strength.

Green Silicon Carbide

Green Silicon Carbide (SiC) is the product of silica quartz sand and petroleum coke electrofused at high temperature in an arc furnace. The sharp, blocky grains of Green Silicon Carbide are highly pure and have extreme hardness (Mohs 9.4 / Knoop 2600), strong cutting capacity, stable chemical properties, excellent thermal conductivity, and high strength at high temperatures.

Applications

  • Abrasives: Used to manufacture high-quality vitrified, resin-bonded, and coated abrasives products such as grinding wheels, honing stones, and sheet materials.
  • Blasting: Used in the form of both grains and powders.
  • Polishing: Used as a component of lapping and polishing compounds.
  • Cutting: Used in both water-jet and wire-saw cutting.
  • Electronics: Used in the production of LEDs and in semiconductor devices that operate at high temperatures or high voltages or both.
  • Ceramics: Silicon Carbide grains are sintered to produce very hard ceramics for applications that require high endurance, such as automobile brake and clutches, wear-resistant seals/rings/nozzles, coatings, metal-matrix composites, kiln furniture, ceramic plates in body and vehicle armor, silicon carbide heating elements, and many more.
  • Steel Production: Because of its purity and composition, Silicon Carbide used as fuel improves yields and adjusts materials content in processing steel scrap, producing cleaner steel with lower emissions.
