Purple Tungsten Phase Component Reduction Process

Violet tungsten phase component WO2.72 (or W18O49), purple tungsten (TVO) powder having a maximum of pore volume, a minimum micropore volume, the narrowest pore size distribution, the smallest and the largest fractal dimension average pore diameter, which Hydrogen Reduction in favor of ultra-fine tungsten powder, to the detriment of the doping process, is a unique crystal structure so used to produce fine powder and fine tungsten carbide powder.

Performance is mainly determined by the quality carbide WC powder. The final grain size of the WC powder grain largely by reduction of the metal tungsten powder determined, while the grain is made of metal tungsten powder and tungsten oxide reduction condition is determined. Therefore, performance and purple tungsten oxide reduction process can affect the performance of tungsten and tungsten carbide powder, which ultimately affect the quality of the carbide.

Restore purple tungsten (V- tungsten oxide or WO2.72), the reduction of the product in different temperature ranges were under scanning electron probe to observe the phase composition seen in the temperature range of 885 ~ 900 ℃: the purple tungsten as raw materials in the reduction The key process tungsten dioxide reduction process is not controlled tungsten powder (T-W) particle morphology; process without passing through the tungsten (WO2) dioxide generated intermediate stage, can produce ultra-fine or micrometer tungsten, tungsten carbide powder .
