temperature of 1930 C. The specimen with 25 wt. % of sintering additives gave the maximum value of hardness of 2601 HV. Keywords: silicon carbide, ceramics, sintering, microstructure, mechanical properties. INTRODUCTION For decades, silicon carbide
Silicon carbide powders are utilised for abrasive machining processes such as grinding, sandblasting, and water-jet cutting. SiC can be laminated in paper, cloth, or wood to produce frictional grip. It can also be used for shaping, honing, and polishing other materials.
Corrosion characteristics of silicon carbide and silicon nitride
tion bonding technique, carbon, siHcon metal, sili- con nitride, or other powders may be mixed with silicon carbide powder and allowed to react at high temperature. The resulting ceramic is generally a multiphase material that also may have a bimodal SiC grain
Titanium carbide is the binary compound and is an extremely hard refractory ceramic material ( Mohs 9-9.5) similar to tungsten carbide. It is the only carbide in the titanium - carbon system. Like Tungsten Carbide (WC) and Tantalum Carbide (TaC), it is also an important component of cemented carbides used for cutting tools.
