Product Description Product DescriptionBlack Silicon Carbide (SiC) is an extremely hard (Mohs 9.1/ 2550 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 Al203 ). 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. Physical PropertiesSilicon carbide (SiC) is an important abrasive because of its great hardness, but its range of applications exceeds that of ordinary abrasives. For example, its high temperature resistance and thermal conductivity make it one of the preferred kiln materials for tunnel or shuttle kilns, and its electrical conductivity makes it an important electrical heating element.The first step in the preparation of SiC products is to prepare SiC smelting blocks [or: SiC granules, which were once known as: adamantine because they contained C and were super hard. However, it is important to note that it has a different composition to natural adamantine (also known as: garnet). In industrial production, SiC smelting blocks are usually made of quartz, petroleum coke and other raw materials, auxiliary recycling materials, spent materials, after grinding and other processes to become a reasonable proportion and particle size of the appropriate furnace material (in order to adjust the permeability of the furnace material need to add the right amount of wood chips, the preparation of green silicon carbide also add the right amount of salt) prepared by high temperature.
