摘 要：亚稳态六方三氧化钨化合物 (h-WO3)能否合成是一个颇有争议的问题 ,需要进一步探讨h-WO3 的存在形态 .作者研究合成了一类新的亚稳态六方钨氧化合物 (h-(NH4 ) xWO3) ,结果表明 :必须有NH+4 存在才能形成h WO3;h-(NH4 ) xWO3 在有机相和水相介质中的掺杂反应说明 ,K+和Na+均可取代h-(NH4 ) xWO3 中的NH+4 .分析了这种反应机理及应用前景 .
Abstract: There is a lot of disputation about the h WO3 compound; it is necessary to make further scientific experiment. The new hexagonal tungsten oxide compounds (h-(NH 4) x WO3) were prepared; it was demonstrated that NH 4 ion makes h-WO3 compound stabilized. Doping reaction of h-(NH4) x WO3 in organic medium and in aqueous solution indicated that NH 4 ion was displaced by K and Na ions; and displacement mechanism was investigated. There may be a good prospect for industrial application of oxidized ammonium tungsten bronze (h-(NH4)x WO3) in production of doped tungsten wires.
