对采用APT为原料 ,在湿氢条件下进行氢还原制备细颗粒活性氧化钨—紫钨的工艺进行了研究。结果表明 ,紫钨的生成条件与还原温度、氢气湿度、升温速度、原料粒度、料层厚度等因素有关 ,紫钨的粒度随还原温度的升高、氢气湿度及升温速度的增大、原料粒度及料层厚度的增大而增大。实验中以APT (10 μm)为原料 ,在pH2 O∶pH2 =1.7∶1,2h内温度升至 1173K ,在 1173K保温 1.5h的条件下 ,直接还原获得粒度为 2 .2 μm的紫钨。 The process of preparing fine-grained active tungsten oxide-tungsten oxide by hydrogenation using hydrogen peroxide (APT) as raw material was studied. The results show that the formation conditions of purple tungsten and the reduction temperature, hydrogen humidity, heating rate, raw material size, material thickness and other factors related to the size of purple tungsten with the reduction temperature, hydrogen humidity and heating rate increases, the particle size And material layer thickness increases. In the experiment APT (10 μm) was used as the raw material, and the temperature was raised to 1173K in pH2 O: pH2 = 1.7:1,2h, and the purple tungsten with particle size of 2.2 μm was obtained by direct reduction at 1173K for 1.5 h.
