Using modern physical and chemical methods of research, such as differential thermal analysis, scanning electron microscopy, atomic absorption spectrometry, the recovery process titanium dioxide with calcium hydride at different temperatures and the stoichiometric ratios of the raw material was studied. The influence of experimental conditions on the chemical and particle size distribution of the synthesized product have been established. The mathematical dependence of the qualitative composition of titanium powder from the reduction temperature and the stoichiometric ratio of the starting components was obtained. According to the results of the experimental data revealed that the increase in diameter of grains and reducing the specific surface area of the synthesized powder increases the content of titanium in the sample. It is shown that the main problem of obtaining titanium powder is their increased oxidation caused by high specific surface
