SILICON CARBIDE (SiC) BALLS Ceramic balls with good mechanical and stiffness properties, good corrosion and wear resistance. They are electric conductors and suitable for high temperature applications. Applications Special bearings and pumps, electric switches and sensors, medical instruments. They are used in automotive, aviation and aerospace, naval, petroleum, chemical and electronic industry. Commercial name Other name Formula Carbide % Silicon Carbide Carborundum SiC 99.9
Silicon Carbide has properties remarkably similar to those of diamond – it is one of the lightest, hardest, and strongest technical ceramic materials and has exceptional thermal conductivity, resistance to acids, and low thermal expansion. Silicon Carbide is an excellent material to use when physical wear is an important consideration because it exhibits good erosion and abrasive resistance, making it useful in a variety of applications such as spray nozzles, shot blast nozzles and cyclone components.
