Abstract: A new process is studied to synthesize an intermetallic compound TiCr2 directly from the oxide mixture of Cr2O3 and TiO2. This method combines the calciothermic co-reduction and the in situ dissolution of the by-product CaO into the molten salt. The molten CaCl2 was needed to dissolve CaO for complete reaction, and the reduction and alloying occurred simultaneously and quickly in this media. Because of the narrow compositional range of TiCr2, however, a small amount of Ti and Cr coexisted with α-TiCr2. The high temperature form, β-TiCr2, was not found probably because it decomposed into α-TiCr2 and Cr during cooling. The obtained alloy powder showed capability of hydrogen storage after activation.
