1) it is an extremely hard refractory ceramic material, similar to tungsten carbide, it provides higher activity, lower sintering temperature, higher ductile & strength and 80% higher reflection of uv light. 1) it can be used as abrasives, enhancement or particle coats, can improve wear resistance, toughness and hardness of hard alloys, bearings alloy, nozzles, cutting tools, tool bits. Nano ceramic composited with tin, wc, al2o3 especially for petrochemical & refractory uses. The resistance to wear, corrosion, and oxidation of a tungsten carvide-cobalt material can be increased by adding 6% of tic to tungsten carbide. Tool bits without tungsten content can be made of titanium carbide in nickel-cobalt matrix cermets, enhancing the cutting speed, precision, and smoothness of the piece. This material is used as a heat shield for atmospheric re-entry of space shuttles and similar vehicles. The substance may be also polished and used in scratch-proof watches.
