通过在蓝钨中加入钼酸铵水溶液,研究了钼对还原钨粉粒度的影响。随钼添加量的增加,钨粉愈细;钼在钨粉中主要以单质存在。分析了钼抑制钨粉晶粒长大的作用机理。
The effect of molybdenum on the particle size of reduced tungsten was studied by adding ammonium molybdate in blue tungsten. With the increase of molybdenum content, the finer the tungsten powder; the molybdenum in the tungsten powder mainly exists as a simple substance. The mechanism of inhibiting the grain growth of tungsten powder by molybdenum was analyzed.
