一、前言 APT热分解制取蓝钨机理的研究与应用,有关学者已进行过广泛的探索和讨论。但在APT制取蓝钨工艺过程中,氨的分解与氨分解触媒介质的探讨;氨分解新生活性原子态氢的还原作用;蓝钨物相形貌演变过程及机理的讨论尚末引起人们注意。 I. Introduction APT thermal decomposition of blue tungsten mechanism of the research and application, the scholars have conducted a wide range of exploration and discussion. However, during the process of preparing blue tungsten by APT, the discussion of ammonia decomposition and ammonia decomposition catalyst media; the reduction of new atomic hydrogen by ammonia decomposition; the evolution process and mechanism of the phase morphology of blue tungsten did not cause people note.
