摘　　要：蓝钨是制备钨粉的主要原料之一,其物理性能直接影响钨粉的物理性能,本研究采用自还原法生产蓝钨,选取不同物理性能的APT作为原料,调整煅烧温度、给料速度、炉管转速三个工艺参数,通过性能表征发现以上工艺参数对蓝钨的粒度、松装密度、氧指数、比表面等均有影响。Blue Tungsten oxide is the main raw material for the preparation of tungsten powder,and its physical properties directly affect the physical properties of tungsten powder.In this study,the Blue Tungsten Oxide was produced by selfreduction method,and the ammonium paratungstate with different physical properties is selected as the raw material,and then the calcining temperature,feeding rate and furnace tube rotational speed are adjusted,the effect of the above process parameters on the physical properties of Blue Tungsten was studied by characterization.
