The effect of batch size and purity of raw materials on the yield and the properties of TiB/sub 2/, prepared by heating in vacuum a mixture of TiO/sub 2/, B/sub 4/C, and charcoal, was investigated. It was found that the temperature must be increased to 1700 tained C as the batch size is increased, while keeping the pressure at 1.10/sup -4/ mm of Hg. Using the stoichiometric ratio of C: B = 0.276, the reaction is not connpleted and the end prcduct will conthin an insoluble residue. Impurities in the starting materials, such as Si, Fe, Al, and Mn are removed during soaking at high temperature in vacuum and do not influence the purity of the end prcduct as was shown by spectrographic analysis; on the other hand, Mg and Co are harder to remove. Results show that technical TiO/sub 2/ and B/sub 4/C may be used for preparing pure TiB/sub 2/. (TTT)
