The technology of carbothermic reduction of titanium and boron oxides in the TiО₂-B₂О₃-C reaction mixture at temperatures up to 1070°C is presented. The temperature and atmospheric regimes of low-temperature reduction of TiO₂ are determined. In the Ti-B-O-C system, successive phase formation of TiО₂→Ti_nO_2n-1→TiBО₃→TiC_xO_1-x→TiB₂ at 1030 ÷ 1050°C was realized, which was recorded by X-ray phase analysis of the samples after synthesis. The conditions for the realization of low-temperature synthesis are established, which consist in observing the prescriptions and special regimes for preparing the reaction mixture, the conditions for heating and holding the samples in a controlled atmosphere. For discussion, the mechanism of oxycarboboride phases formation at each of the stages of reduction of activated titanium oxide is presented. The principal possibility of low-temperature synthesis of TiB₂ in the composition of carbon-graphite products by free pitch technology in the conditions of existing kilns is shown.
