摘要
本文提出了一种既能降低生产成本又能减少制备活化原料麻烦的制取粗晶粒钨粉的新方法,即“焖氢”还原法.试验表明,该方法可使钨粉粒度增粗1倍,其生产成本比高温还原工艺低。
This paper presented that a new method of preparing coarse grain tungsteu carbide powder, that is 'depression hydrogen'reduction process. Testing resulrs showed that the process enable tungsten powder particle size increase one-fold,and the production cost is reduced than high-temperature reduction process.
