Descriptions
Silicon carbide is the lightest and hardest material - similar to diamond - within the field of technical ceramics. In addition, silicon carbide displays good thermal conductivity, low thermal expansion and very good resistance to acids and alkalis. Since the properties of the material remain constant at temperatures of up to 1,400°C and it is also extremely light and stable in form, silicon carbide is outstandingly suitable as a construction material.
Components made of silicon carbide are for example used in chemical plants, as semiconductor material and in the field of optics. The material is also suitable for use within the foodstuffs industry. Generally, silicon carbide is suitable for use in demanding applications. In comparison with metal, the material offers very economical and durable solutions.
Green Silicon Carbide (SiC) is an extremely hard (Mohs 9.4 / 2600 Knoop) man made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al2O3). SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2600°C.
Micro Grit Green Silicon Carbide is made by a precision water classification process using material that is produced from the reaction between high purity silica sand and petroleum coke in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.
HIJO Abrasives offers a whole range of macro and micro grits in green silicon carbide, quality and various particle size distributions based on FEPA, and JIS standards.
