Tungsten carbide mechanical seals were once the go-to choice, but have since been overshadowed by silicon carbide’s rising popularity. This blog will compare both types and highlight its numerous advantages over its counterpart tungsten carbide mechanical seals. Advantages of this unique material include its premium hardness rating of 9.5 on the Mohs scale, exceptional corrosion …
Alpha silicon carbide, a hard chemical compound with a hexagonal crystal structure, is often used as an insulation material and in refractories. Due to its density and self-sharpening capabilities, alpha silicon carbide also makes an excellent material for wire sawing applications. Due to its low neutron cross-section and resistance to radiation damage, silicon carbide makes …
Silicon carbide (SiC) is one of the world’s premier ceramic materials with numerous industrial applications due to its superior thermal and chemical stability. SiC boasts many desirable characteristics such as high strength and hardness, corrosion resistance, refractoriness and great wear resistance – qualities which have led to widespread adoption worldwide. Edward Goodrich Acheson first synthesized …
Silicon Carbide (SiC) is an extremely hard crystalline compound composed of silicon and carbon that occurs both naturally as moissanite mineral, as well as being manufactured synthetically as an abrasive. Produced from powder that has been mixed with non-oxide sintering aids, extrusion or cold isostatic pressing (plates and blocks) is used to shape it. This …
Silicon carbide schottky diodes have become an increasingly popular component in new electronic circuit designs, especially power system applications. Their advantages include increased efficiency levels and faster switching speeds; better form factors for overall circuit designs and lower switching times overall. When metal contacts SiC, a Schottky barrier forms and current flows in one direction …

Hot surface ignitors are replacing spark ignition in modern furnaces. Constructed of silicon carbide or silicon nitride with ceramic bases to encase wire connections, 120-volt hot surface ignitors create red-hot glow before arcing over to light the gas in combustion cycles. Engineers who designed these units had some important decisions regarding where the ignitor should …

Silicon carbide armor is commonly used to defend military and law enforcement personnel against bullets or other high-velocity projectiles, providing crucial protection. It absorbs and dissipates impact energy to help prevent injuries or deaths during high velocity impacts. Material used in this defense solution is proven effective against armor-piercing rounds and high velocity fragments, and …
Silicon carbide electrical conductivity is an indispensable quality in modern high-tech applications, helping drive performance and reliability without degrading function or safety. Thanks to its chemical resistance properties, silicon carbide can operate under extreme conditions without degradation that compromises function or safety. Doping can alter the electrical conductivity of SiC by adding impurities known as …
Silicon carbide X4 features high hardness and rigidity, making it suitable for use as a grit in sandpaper or sharpening knives, while being easier to work with than steels that contain Vanadium such as S90V. Conventional computer chips are manufactured by using cooling techniques to solidify pure silicon molten. Unfortunately, this process can sometimes result …
