摘要
对于氧化钨的研究,国内外大部分研究很少有关于氧化钨原子结构方面的研究,尤其在国内这一点更加接近于空白状态。本文第一次从原子结构上进行研究和探讨,用来解释和分析宏观状态所表现的特征。我们提出原位还原机理将,即氧化钨以原子晶胞结构为基本,在还原驱动力下,逐步失去氧原子,晶胞结构没有发生较大变化,而被还原成钨。同时基于传统的氧化钨的还原过程中挥发沉积理论,相对比较细致的提出和诠释了原位还原机理理论在氧化钨还原过程中的存在,同时伴随着挥发沉积理论,二者共同存在。
Most of the researches of Tungsten Oxide home and abroad,are seldom studying on the atomic structure of Tungsten Oxide.Especially at home the studies of the structure almost close to the blank space.For the first time to research and discuss the atomic structure of Tungsten Oxide,the purpose is trying to explain and analyze the characteristic of the macrostate.We propose the reduction in situ,that is on the basic of unit cell structures of tungsten oxide,at the driving force of reduction,which lose the oxygen atoms step by step,unit cell structures have no larger change,then they are reduced to tungsten.Meanwhile,at the base of the traditional volatilization and deposition of Tungsten Oxide,detailedly propose and explain the mechanism of reduction in situ in the process of the reduction of Tungsten Oxide,at the same time,the volatilization and deposition are also happen,the two mechanisms are both exist.
