Silicon carbide coatings provide an impervious barrier that protects graphite components used for MOCVD, EPI and semiconductor manufacturing from oxidation and chemicals. CGT Carbon’s PERMA KOTETM high purity silicon carbide coating protects graphite components used in MOCVD, EPI and semiconductor production environments. Coating preparation methods must be carefully chosen based on performance requirements and substrate …
Silicon carbide, an extremely strong mechanical material used across numerous industrial applications, is increasingly being utilized. Its hardness surpasses that of its rival tungsten carbide. Most silicon carbide is produced using the Acheson Process, created accidentally by Edward Goodrich Acheson while trying to produce synthetic diamonds. It is the easiest and simplest way of producing …
Silicon carbide is an exceptionally resilient material, capable of withstanding high temperatures without disintegrating, as well as boasting exceptional chemical stability and castable properties. Neutron strain scanning allowed researchers to quickly and precisely measure elastic strain in circular ceramic samples under controlled conditions, with measurements taking place along one direction (normal to the surface) for …
People frequently start by rough sanding raw woods or metal with aluminum oxide abrasives before moving on to silicon carbide for light pressure sanding between coats. Nonwoven abrasives like belts, discs, and wheels often contain both materials. Zirconia lasts longer and is more friable than aluminum oxide, yet comes at a premium cost. It works …
Silicon Carbide (SiC) is an exceptionally durable ceramic material, boasting superior thermal stability, electrical conductivity, chemical resistance, extreme hardness, low expansion rates and being ideal for space telescope mirrors. Schunk Carbon Technology has developed an innovative process for 3D printing with silicon carbide that offers greater design freedom and increased reliability. Binder jetting Binder jetting …
Silicon carbide knives offer several advantages over natural or aluminum oxide sharpening stones, which require constant water lubrication while sharpening. Carborundum (also referred to as green silicon carbide or SiC) is an abrasive material often used for sharpening, deburring and cleaning precious metals and gemstones. Hardness Silicon Carbide (SiC) is an incomparably hard material composed …
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 …
