The production of metallic titanium has been studied recently by many investigators. Of the methods suggested, the Kroll process, which is to reduce titaniumtetrachloride with magnesium, has only been carried out on industrial scale, but this process seems to have many difficulties in operation. While attempts at electrolytic production of metallic titanium from fused salts have been tried by some investigators, any successful method has not yet been established. Although there is a possibility of electrolytic production of titanium from fused salts, this method has many difficulties regarding electrolytes. From this point of view, the authors performed experiments on the electrolytes. Experiments were carried out to determine the melting points of binary or ternary fused salts chiefly composed of K_2TiF_6 and the solubility of TiO_2 in the fused salts. The following results were obtained : (1) In alkali double flurorides of titanium, K_2TiF_6 was prepared easily, but the decomposition of this compound at high temperature could not be prevented in the presence of moisture. (2) The eutectic point of the binary systems were determined as follows : [table] (3) About 3% of TiO_2 was soluble in fused K_2TiF_6-NaCl electolyte within the range from 30 to 70% NaCl. (4) About 5% of TiO_2 was soluble in K_2TiF_6-NaF electrolyte and the melting point of fused salt was rised as the quantity of TiO_2 increased.
