The paper presents and substantiates the technology of carbothermic reduction of titanium and boron oxides in the composition of reaction mixture in TiO2 - B2 O3 - C at the temperatures up to 1070 °C. The initial components of the reaction mixture were titanium and boron oxides in a hydrated form of metatitanate (H2TiO3 = TiO2 .H2O) and boric (H3BO3 = 1/2B2O3 .3/2H2O) acids which made it possible to use "wet" methods of mixing of reactants to increase the reaction surface, first and foremost the Sol-gel technology. The possibility of a low-temperature synthesis of titanium diboride was substantiated by the theory of increased reactivity of compounds in the transformation period of the crystal lattice during phase transitions. A technology was developed and implemented for transfering of anatase-rutile transformation (ART) of titanium oxide from the temperature interval 600-800 °C to the range of 1030-1050 °C of a phase formation development in a Ti - B - O - C system. A research was conducted on preparation (doping) of TiO2 by the Sol-gel technology for modification of an amorphous titanium oxide through fluorine according to the TiO2XH2O → TiO(OH)2-xFx↓ → TiO2-xFx → α-TiO2-xFx scheme. The temperature intervals of anatase-rutile transformation of titanium oxide in different gas environments were determined. It is shown that conducting the process in vacuum and argon stimulates the transition of ART, including doped titanium oxide. On the other hand, a stable state of the doped anatase α-TiO2-xFx and the state of ART that enables an active interaction can be preserved in an oxygen-containing atmosphere with a temperature up to 1100 °C. The temperature and the atmospheric mode of carbothermic reduction of TiO2 were specified. A sequential phase formation of TiO2 →TinO2n-1 →TiBO3 → TiCX O1-x → TiB2 was realized in a Ti - B - O - C system at 1030-1050 °C, which was recorded by X-ray diffraction (XRD) of the samples after synthesis. The conditions were established for implementation of low-temperature synthesis. They are in compliance with recipes and special modes of the reaction mixture preparation, conditions of heating and cooling of samples in a controlled atmosphere. A mechanism of formation of oxy-carbo-boride phases in each stage of the recovery of the activated titanium oxide is presented for purposes of discussion.
