摘要	Self-propagating high-temperature synthesis(SHS) with reduction process was used to fabricate tungsten powder from the system CaWO4-Mg. The physico-chemical change during heating and the effects of pressure of sample and diluent on product have been studied. The experimental results show that with increasing pressure of sample, the porosity of combustion product and the particle size of final tungsten powder decrease. Additive diluent could increase the particle size of final tungsten powder. The purity of tungsten is improved by leaching in NaOH solution. The results of spectral analysis and particle size distribution of final tungsten powder show that the final W powder has median diameter of 0.87 mum, Specific surface area of 1.09 m(2)/g and purity of above 99.0%.
