Fine Tungsten carbide powder has high purity, uniform particle size and good dispersibility. It has the surface electronic properties of platinum, which can be used as a catalyst in some organic reactions.
Preparation
Use metal tungsten powder and carbon black as raw materials, mixture in a certain proportion, the mixture into graphite boat, placed on a carbon tube furnace or high sense of intermediate frequency electric furnace, carbonized under a certain temperature, then through ball mill, screening. Finally, fine tungsten carbide powder was prepared.
Applications
Fine tungsten carbide powder has similar platinum surface electronic properties, It can replace platinum and other precious metals as catalysts and is used in some organic reactions, such as hydrocarbon catalytic hydrogenation/dehydrogenation, isomerization of hydrocarbon, hydrocarbon conversion, hydrocarbon synthesis, hydrazine decomposition, oxidation reaction and the catalytic properties of synthetic ammonia reaction, etc.
