What is a Silicon Carbide Product
Silicon carbide (SiC), also known as carborundum or SiC,. is one of the lightest, hardest, and strongest technical ceramic materials. It has exceptional thermal conductivity, resistance to acids, and low thermal expansion.
Since the late 19th century, silicon carbide ceramics have been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found application in refractory linings and heating elements for industrial furnaces, in wear-resistant parts for pumps and rocket engines, and in semiconducting substrates for light-emitting diodes.
Advantages of Silicon Carbide Products
Silicon carbide products have superior properties such as low density, low thermal expansion, oxidation resistance, excellent chemical resistance, high thermal shock resistance, high wear and hardness resistance, high strength, high-temperature resistance, and high-temperature strength.

Application of Silicon Carbide Products
Until the invention of boron carbide in 1929, silicon carbide was the hardest synthetic material known. It has a Mohs hardness rating of 9, approaching that of a diamond. In addition, SiC crystal has fracture characteristics that make them extremely useful in grinding wheels and in abrasive paper and cloth products.
Its high thermal conductivity, together with its high-temperature strength, low thermal expansion, and resistance to chemical reaction and thermal shock, makes silicon carbide valuable in the manufacture of high-temperature bricks and other refractories.
SiC ceramic is also classed as a semiconductor, having an electrical conductivity between that of metals and insulating materials. This property, in combination with its thermal properties, makes SiC a promising substitute for traditional semiconductors such as silicon in high-temperature applications.
