Morphology Change of Al_2O_3-doped Molybdenum Alloy Powders AITranslate
Abstract AITranslate
Alumina-doped molybdenum powders were prepared by hydrothermal synthesis combined with low-temperature calcination and two-stage reduction, and mass fraction of Al2O3 were 0,0. 25%,0. 5%, 0.75% and 1% in the molybdenum alloy powders. The morphology and phase composition of molybdenum alloy powders were analyzed using SEM and XRD,respectively. And the influence of A12 Oa dosage on mo- lybdenum alloy powders was investigated at different preparation stages. The results show that Al2O3 dos- age has a certain effect on the uniformity, particle distribution and particle size of the powders. Increasing Al2O3 content has dispersion effect on aggregation of molybdenum alloy powders. After two-stage hydro- gen reduction, flaky MoOa particles is completely reduced to spherical Mo particles,and the mixed powders are mainly composed of Mo and a-Al2O3 without other phases, α-Al2O3 can refine the molybdenum parti- cles ,and the refinement effect of molybdenum particles is more obvious with alumina increasing.
