| titleOfInvention | Method for preparing ultrafine tungsten carbide powder using molten salt introduced autorotation |
| abstract | Ultrafine WC powder production method according to the present invention is tungsten oxide; reducing agent; Carbon source; Alkali salts which are particle growth inhibitors; And a self-propagating High-temperature Synthesis (SHS) of the raw material containing a reactive containing; has the characteristics of producing ultra-fine WC powder.n n n In the production method of the present invention, an ultrafine tungsten carbide powder having an average particle size of 0.05 μm to 0.5 μm may be prepared, the particle size of the powder may be controlled in units of submicron, and the particle size distribution of the prepared powder is narrow, and the purity is high. It has the advantage of being very high (more than 99%), and compared to other manufacturing processes, the reduction and carburizing reaction of tungsten oxide is performed in one step, so the process is simple, the process time is short, the thermal efficiency and productivity are excellent, There is an advantage that can be greatly reduced.n n n n Tungsten Carbide, High Temperature Synthesis Method, Rotating Burning Reaction, Ultrafine Powder, Tungsten Oxide |
