A Study on Ultrafine Tungsten Powder Produced for the Ultrafine Hard Metals From Violet Tungsten Oxide by Hydrogen Reduction Techniques

In this article two kinds of tungste n oxide materials of violet tungsten oxide and tungsten blue oxide were selected to study the influence of ra w materials on ultrafine and homogen ous tungsten powder.Researching re sults showed that tungsten powder has loose structure produced in violet tungsten which is more suitable for the ult rafine hard metals.
