Abstract
Behaviors of TiO2 in the alumina carbothermic reduction and chlorination process in vacuum at different temperatures were investigated experimentally by means of XRD, SEM and EDS. In the preparation of materials, the molar ratio of Al2O3 to C was 1:4, and 10% TiO2 and excess AlCl3 were added. The results show that TiC is produced by C and TiO2 after TiO2 transforms from anatase into rutile gradually. In the temperature range of 1 763-1 783 K, the compounds of Ti and Al are not found in slags and condensate. The purity of aluminum reaches 98.35%, and TiO2 does not participate in alumina carbothermic reduction process and chlorination process in vacuum.
