【摘要】 钨金属硬度高，熔点高以及耐磨性优良，抗电子迁移能力强，广泛应用于工业的各个领域。目前工业上制取钨粉的方法普遍为氧化钨氢还原法，该方法清洁简单，但由于影响因素的繁杂和氢分子的难以检测，其还原机理特别是氢还原氧化钨的动力学机理尚待研究，制取均匀粒度超细钨粉技术参数的确定也有待科研者的努力。本文总结了氧化钨的氢还原现阶段的热力学、动力学机理和适用的动力学模型，并展望了利用计算机模拟技术进一步探究动力学机理和微观机理的方法。更多还原

【Abstract】 Tungsten metal is widely used for its high hardness,high melting point 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.更多还原
