FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry and metallurgy. Method of producing titanium diboride powder involves preparing a wet reaction mixture by hydrolysis of titanium tetrachloride in distilled water while stirring continuously to obtain hydrated titanium dioxide and hydrochloric acid while adjusting acidity by adding ammonium hydroxide NH4OH to pH from 7 to 8. Hydrated titanium dioxide is modified with chlorine to obtain a complex of metatitanic acid. With constant stirring, boric acid and sucrose are added in amounts providing super stoichiometric ratio C/TiO2+B2O3 about 0.5 wt% to obtain hydrated titanium dioxide and hydrochloric acid. Method includes carbothermal reduction of reaction mixture at heating from 950 to 1,000 °C with holding in atmosphere of dynamic vacuum for 3–4 hours.
EFFECT: invention provides higher efficiency of production of titanium diboride powder, simplified process of producing titanium diboride powder and low synthesis temperature.
