摘要
在熔融CaCl2 体系中 ,采用自制球团状TiO2 阴极进行了直接电解还原制取海绵钛的实验 ,结果表明 :在电解温度 90 0℃ ,槽电压 3.0V下电解可以得到海绵钛 ,石墨阳极上有氧气放出 .电子探针分析表明 :阴极产物的形貌为海绵状 ,其Ti含量为 94.646% .
A study of the direct electrolysis reduction of pellets of TiO 2 to titanium in molten CaCl 2 has been made. The result shows that sponge titanium can be gained for several hours under the condition of electrolytic temperature 900℃ and voltage 3.0?V , and O 2 emitted from the graphite anode. The EPMA analysis reveals that the image of the microstructure in cathodal products is sponge and the content of titanium is 94.646%.
