| 摘要: 关于CaO与WO3及MoO3的固相反应机理已有文献报道.Flor等认为该反应受高价态钨离子和O2-离子扩散所支配.Jae等为了获得金属钨,在900～1200℃将WO3溶解于CaO和CaCl2中,采用石墨电极进行熔融电解时,发现有WO2Cl2生成.但有关CaCl2与WO3及MoO3的固相反应 |

| Abstract: The solid state reaction of WO3 with CaCl2 has been studied by the method of thermal analysis.The chemical behavior of reaction process was indicated by TG and DTA curves.The reaction is governed by the diffusion of Ca2+、 Cl-、WO42-、 WO22+ ions,CaWO4 and WO2C12 are formed.The reaction products were characterized by powder X-ray diffractfon method. |
