Green Silicon Carbide

The raw materials for our products come from the silicon carbide production base in northwest China. Green silicon carbide is made of petroleum coke and high quality silica as the main raw material, with salt as an additive, and smelted by high temperature in resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum. It is suitable for processing cemented carbide, glass, ceramics and non-metallic materials, and is also used for semiconductor materials, high-temperature silicon-carbon rod heaters, far-infrared source substrates, etc.

Green silicon carbide manufacturing method is the same as black silicon carbide, but the purity of the raw materials used requires a higher degree of purity, also formed in the resistance furnace at a high temperature of about 2200 ° C, green, translucent, hexagonal crystal shape, its Sic content is higher than black, physical properties and black silicon carbide similar, but the performance is slightly more brittle than black, also has a better thermal conductivity and semiconductor properties.

Physical properties

  • 1. Green color, content of 98% or more, high hardness, strong cutting ability, stable chemical properties, good thermal conductivity. Microscopic shape of hexagonal crystals, silicon carbide Mohs hardness of 9.2, Weiss microhardness of 3000 – 3300 kg / mm
  • 2.  Nuptial hardness of 2670-2815 kg/mm, microhardness of 3300 kg per cubic millimeter. It is higher than corundum and second only to diamond, cubic boron nitride and boron carbide in abrasives. Density is generally considered to be 3.20 g/mm
  • 3. The natural bulk density of silicon carbide abrasives is between 1.2 – 1.6 g/mm3, with a specific gravity of 3.20 to 3.25.

Main Uses

  • Solar silicon wafer, semiconductor silicon wafer, quartz chip cutting and grinding;
  • Crystal, pure grain iron polishing;
  • Ceramics, special steel precision polishing;
  • Sandblasting.
  • Solidification and coating abrasives, cutting, free grinding and polishing;
  • Also can grind glass, stone, agate and high-grade jewelry and jade and other non-metallic materials,
  • And can manufacture high-grade refractory materials, engineering ceramics, heating elements and thermal components.

Green silicon carbide, suitable for processing carbide, glass, ceramics and non-metallic materials in addition to semiconductor materials, high-temperature silicon carbide rod heaters, far-infrared source substrates, etc.

Green silicon carbide micro powder refers to the micronized silicon carbide powder which is classified by ultra-fine powdering using JZFZ equipment. At present, silicon carbide micronized powder is mainly 1200# and 1500#. Since silicon carbide micronized powder is mainly used in the abrasive industry, there are special requirements for the classification of micronized powder, and no large particles can be present in the micronized powder, so in order to meet the international and domestic product requirements, the general production uses JZF classification equipment for classification.
