Investigation on Preparation of Coarse Crystal W Powder through Li activated H 2 Reduction of WO 3 AITranslate
Abstract AITranslate
Li activated H 2 reduction of WO 3 is carried out in four steps. During reduction of WO 3 with 200×10 -6 lithia at 900-950℃, the reduction duration can decrease by ~20%,The activation is greatly shown in the step of WO 2 W. The coarsening of W powder size and the effect of Li addition are clearly indicated in the step of WO 2.72 -WO 2,particularly in the step of WO 2-W. The mechanism of activation and grain coarsening during reduction is discussed.
