一、前言“蓝色氧化钨”具有活性好、比表面大、利于掺杂等特性。因此,它是制取抗高温下垂性掺杂钨粉的重要原料。所谓“蓝色氧化钨”系指 WO_(2.90)、W_(20)O_(58)以及(NH_4)_x·WO_3·(H_2O)_y 等多种混合态氧化物之统称,它系 APT 热分解产物。该分解过程是复杂的,其产物的组成、物相结构受多因素影响。虽有不少学者对此进行了大量的理论研究,但迄今尚无定 First, the preface “blue tungsten oxide” with good activity, large surface, conducive to doping and other characteristics. Therefore, it is the preparation of anti-high temperature doping tungsten powder an important raw material. The term “blue tungsten oxide” refers to a variety of mixed oxides such as WO_ (2.90), W_ (20) O_ (58) and (NH_4) _x.WO_3 · (H_2O) _y, which are APT thermal decomposition products . The decomposition process is complex, the composition of the product, phase structure affected by many factors. Although many scholars have done a lot of theoretical research, but so far no fixed
