摘 要:<正> The hydrogen reduction of tungsten oxides WO2.90,W20O58 and WO3 were directly studied using high temperature X-raydiffraction analysis.The differences between tetragonal WO2.90 and monoclinic W20O58 were discussed.Pure β-W was obtainedfrom oxide WO2.90,while there appears small amount of WO2 during the reduction of W20O58 to β-W.
