摘要
以3种不同二钼酸铵(ADM)做原料,采用氢气做还原剂的两段还原法制取钼粉,研究了在相同实验条件下,不同物理特性的ADM对钼粉粒度的影响及在原料相同情况下,还原温度、氢气流量、炉管气氛等工艺因素对钼粉粒度的影响。
Molybdenum powders were made by two - stage hydrogen reduction with three different ammonium molybdates as raw materials. The effect of ammonium molybdate on the grain size of Molybdenum powder is studied under the same experimental conditions. At the same time, the experiment research that the reduction procession such as reduction temperature, hydrogen flow and furnace atmosphere affect on the grain size of molybdenum powder while raw material is the same.
