FIELD: chemistry.
SUBSTANCE: invention can be applied in production of rutile-structured pigment based on titanium dioxide. The method of obtaining the base for pigment rutile titanium dioxide involves obtaining of source solution containing a titanium compound, addition of effective quantity of a salt catalyst to that solution, preferable addition of a chemical control agent to the solution, solution evaporation for obtaining dry amorphous intermediary product containing a mixture of titanium compounds, and baking of the intermediary product at the temperature under 500°C. Another variant of the method of obtaining the base for pigment rutile titanium dioxide uses eutectic mix of two or more NaCl, KCl and LiCl salts as the salt catalyst, melting temperature of the salt catalyst being lower than baking temperature.
EFFECT: reduction of rutile crystallisation temperature.
