摘    要：本文用X-射线衍射与扫描电镜分析研究了在700～1000℃范围内钨、镍、钴混合氧化物的氢还原。也研究了添加少量镍、钴的钨的低温烧结特性。研究结果表明,采用混合氧化物氢还原取得了满意的结果。

Abstract: The hydrogen reduction of three non-strochiometric of cobalt-nickel-tung-sten mixed oxides has been studied in the temperature range from 700 to 1000℃using X-ray diffraction analysis and scanning electron microscopy. This paperalso deals with low temperature sintering characteristics of tungsten dopedwith small amounts of nickel and cobalt. Research results showed that satis-factory results have been gained by using the hydrogen reduction of mixedoxides.
