Silicon carbide is used in abrasives, in polishing and grinding. It is widely used in appliions calling for high endurance, such as automobile brakes, car clutches and ceramic plates in bulletproof vests. Electronic appliions of silicon carbide are as light emitting diodes and sensors. It is utilized for the production of fertile, transgenic

Silicon Carbide Brick is silicon carbide firebrick whose raw material is black silicon carbide. The content of SiC in silicon brick is about 72%~99%. The good characteristics of silicon carbide brick are high thermal conductivity, good wear resistance and strong acid slag resistance, making it widely used in the lining of alumina electrolysis cell and the furnace lining of electric furnace.

Silicon carbide has a Mohs hardness rating of 9, making it the hardest available material next to boron carbide (9.5) and diamond (10). It is this apparent property that makes SiC an excellent material choice for mechanical seals, bearings, and cutting tools.

In this work, shockless spalling tests have been performed on two silicon carbide grades at strain rates ranging from 10 3 to 10 4 s −1 using a high-pulsed power generator. These spalling tests characterize the tensile strength strain rate sensitivity of each ceramic grade.
Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON bonded and clay bonded. Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process).
Making the Grades Tungsten carbide (WC), also referred to as cemented carbide, is a composite material manufactured by a process called powder metallurgy. Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then sintered in a furnace.
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 diamond. In addition to hardness, silicon carbide crystals have fracture characteristics that make them extremely useful in grinding wheels and in abrasive paper and cloth products.

Boron Carbide (B4C) SINTER-PUR ® Non-Oxide Ceramic Powders Superior Graphite is a key global supplier of high performance sub-micron Silicon Carbide and Boron Carbide powder to the Advanced Ceramics industry, which includes appliions such as ceramic wear parts and ceramic armor.
Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles.

Silicon Carbide. Silicon carbide (SiC) is a synthetic, semiconducting fine ceramic that excels in a wide cross-section of industrial markets. Manufacturers benefit from an eclectic offering of silicon carbide grades due to the availability of both high-density and open porous structures.
Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles.
Pressureless and densely sintered silicon carbide is often used as an inexpensive all-round SiC material for sliding bearings. Not only is it super hard, it also offers good chemical resistance. The SSiC manufactured via solid-phase sintering is particularly suitable for use in sliding bearing components.
With silicon and carbon at their core, these materials are made by coalescing their grades during the sintering process. The result is nothing but the consolidated benefits of both components that no alloy can match. The most noteworthy features of our silicon carbide power products include: • Resistance.
