制备了熔盐电解TiO2制备海绵钛过程中所需的TiO2电极,实验结果表明:在电极制备过程中,各组分质量比量分别为TiO2(锐钛型):聚乙烯醇:H2O=100:5～8:8～10,成型过程中压力控制范围为10～15MPa,烧结温度在900～1300℃之间,烧结时间为4～16h。对TiO2电极质量测试结果表明,按上述工艺制备的电极完全能够满足电解过程的需要。

The TiO2 electrodes for Preparing Spongy Titanium Metal in Melting CaCl2 System were prepared. The results show that the proportion by mass of components for TiO2 electrodes is anatase TiO2 ：PVA：H2O = 100：5 -8：8 ～ 10,the press in molding process should be controlled between 5 to15 MPa, the sinterlng -temperature should be controlled between 900 to 1300℃ ,and the sintering - time should be controlled between 4 to 16 hours. The results also show the TiO2 electrodes prepared by above technics can satisfied the needs of Electrolysis Process completely.
