摘 要: 鎢金屬硬度高，熔點(diǎn)高以及耐磨性優(yōu)良，抗電子遷移能力強(qiáng)，廣泛應(yīng)用于工業(yè)的各個(gè)領(lǐng)域。目前工業(yè)上制取鎢粉的方法普遍為氧化鎢氫還原法，該方法清潔簡單，但由于影響因素的繁雜和氫分子的難以檢測(cè)，其還原機(jī)理特別是氫還原氧化鎢的動(dòng)力學(xué)機(jī)理尚待研究，制取均勻粒度超細(xì)鎢粉技術(shù)參數(shù)的確定也有待科研者的努力。本文總結(jié)了氧化鎢的氫還原現(xiàn)階段的熱力學(xué)、動(dòng)力學(xué)機(jī)理和適用的動(dòng)力學(xué)模型，并展望了利用計(jì)算機(jī)模擬技術(shù)進(jìn)一步探究動(dòng)力學(xué)機(jī)理和微觀機(jī)理的方法。

Abstract:Tungsten metal is widely used for its high hardness, high meltingpoint and excellent wear resistance, strong anti-electron migration capability. At present, tungsten oxide hydrogen reduction is the most common method for tungsten production in industry. However, due to the complexity of influencing factors and the difficulty to detect hydrogen molecules, the reduction mechanism, especially the kinetic mechanism of hydrogen reduction of tungsten oxide, remains to be studied. The determination of technical parameters for preparing ultrafine tungsten powder with uniform particle size also needs the efforts of researchers. In this paper, the thermodynamics, kinetic mechanism and applicable kinetic model of hydrogen reduction of tungsten oxide were reviewed, and the approach of further exploring the kinetic mechanism and micro mechanism by using computer simulation technology was prospected.
Key words: tungsten oxide; hydrogen reduction; computer simulation
