| Abstract: | High-temperature in-situ X-Ray diffracton analysis has been applied to study the dynamic phase transformation process of blue tungsten oxide(W_(20) O_(58) )and yellow tungsten oxide(WO_3) during H_2-reduction.By means of computer data treatment, the dynamic phase transtormation figure and reduction dynamics figure were drawn out quantitatively and automatically.The reduction processes in wet H_2 and dry H_2 atmosphere have beed compared.The reduction mechanism has also been discussed. |
