Silicon carbide abrasives are typically superior in terms of durability and work well for most materials, including metals. Aluminum oxide abrasives offer comparable durability; however, silicon carbide’s harder and sharper nature make it suitable for nonmetallic materials. Friable silicon carbide (in green or black hues) is widely used for polishing ceramics, nonferrous metals and hard […]

Silicon Carbide, or SiC, has an array of applications. It can operate at higher temperatures, frequencies, and voltages than silicon, while providing increased power density. Edward Acheson made an accidental discovery of carborundum while trying to produce artificial diamonds in 1891. By heating clay with powdered carbon using electricity and creating bright green hexagonal crystals

Silicon carbide’s exceptional temperature stability, durability, strength, corrosion resistance and semiconductor properties make it an ideal material for power electronics. Furthermore, doping with phosphorus or gallium could allow doping of an n-type silicon carbide semiconductor base semiconductor device. SiC is available in various polytypes that differ by the arrangement of silicon and carbon atoms in

Silicon carbide provides an outstanding finish in woodworking projects of all kinds. Its heat resistance prevents thermal degradation during intense material removal processes to guarantee consistent performance. Silicon carbide sandpaper excels on harder materials like metal, stone and paint as well as soft ones like rubber, glass and plastic. Due to its friability, however, this

Silicon Carbide (SiC) is an extremely hard industrial material with properties as both semiconductor and ceramic. Found naturally only in moissanite minerals, SiC features close-packed structures composed of four Si atoms bound with four carbon atoms in four-sided tetrahedra that make up its structure; additional polytypes have different physical properties and shapes. Silicone rubber is

Silicon carbide grit features sharp, hard grains that easily cut corners and points for quick cuts at an economical cost compared to diamond or boron carbide grit. Silicon carbide dust can be harmful if inhaled directly. Therefore, appropriate protective equipment such as masks should be utilized and activities involving this abrasive should take place in

Silicon Carbide (SiC) is an advanced semiconductor that overcomes many of the limitations found in traditional silicon devices. With three times wider bandgap than silicon and improved thermal conductivity, SiC devices are ideal for handling higher voltages and temperatures than their silicon counterparts. This article will introduce the basic properties and advantages of SiC that

When selecting a silicon carbide abrasive wheel, various factors must be taken into account, including material type, grit size and severity of grinding. Grain types that can be used include ceramic alumina, zirconia alumina, green silicon carbide and aluminum oxide. Each offers distinct performance characteristics: Alumina is suitable for steel and iron applications while green

Nitride-bonded silicon carbide material boasts high inherent strength and resistance to creep and oxidation at elevated temperatures, making it easy to form near net shapes for applications such as cyclone liners in mineral processing plants or coal plants. At higher temperatures, it has exceptional load-carrying capacities. High-Temperature Strength Nitride-bonded silicon carbide ceramics offer superior temperature

Grinding wheels are tools containing an abrasive-bonded surface which uses various materials to remove material from workpieces. Their type and severity dictate which abrasives, grit sizes and grades must be used depending on what kind of task needs completing. Bonding of the abrasive grains together is of crucial importance, as it affects both speed and
