摘要
以蓝钨为原料,通过氢还原制取超细钨粉末,研究了还原温度、装舟量和氢气流量对制取钨粉粒度的影响。结果表明:还原温度是制取超细钨粉的关键因素,在适当的工艺条件下,可以使用蓝钨制得超细钨粉。
Ultra-fine tungsten powder is prepared by hydrogen reduction from blue tungsten oxide.Research is made on the effect of temperature,boat charge and hydrogen flowrate on granularity of W-powder.The results showed that reduction temperature is critical for the preparation of ultra-fine W-powder from blue tungsten oxide under appropriate technological conditions.
