Silicon Carbide Bricks | Silicon Carbide Refractories

Silicon carbide is segmented into types such as black, green, coated, refractory, metallurgical briquettes, metallurgical, and micro grit. Silicon carbide finds appliion in abrasive cloths and paper products and in grinding wheels owing to its superior properties such as high thermal resistance, hardness, and high temperature strength.

Firing silicon carbide refractories in a nitrogen

During the firing of specimens of silicon carbide and silicon in a nitrogen atmosphere at 1200–1400°C, the silicon is converted almost completely to silicon nitride. The content of impurities of SiO2 and Si varies from 1.7 to 1%, and from 2.8 to 0.5% respectively. The compressive strength of the specimens, depending on the firing temperature, is 2500−1750 kg/cm2, the porosity 17–18%

Silicon carbide │ Technical ceramics

Silicon carbide (SiC) is a high-performance ceramic material made of high-quality, non-oxide powders and can be manufactured to the specific requirements of a wide range of appliions. Due to its excellent tribological properties in coination with low weight, universal chemical resistance and ready availability, SiC is a frequently used

Silicon Carbide Refractories, Nitride Bonded Silicon

Silicon Carbide Refractories. Silicon Carbide refractories are produced from silicon carbide, a raw material synthesized in a resistance-type electric furnace at temperatures exceeding 2500°C, through the reaction of silica with carbon. They have a thermal conductivity ten times that of fireclay refractories, good corrosion and thermal shock resistance, and can be formed into complex shapes.
