Plasma spraying enables to create layers with thickness in a millimeter range adhering on various substrates. This paper provides a study of BaTiO3 coating prepared by atmospheric plasma spraying using a direct current gas-stabilized plasma gun. BaTiO3 was fed into the plasma jet as a feedstock powder prepared by a reactive sintering of micrometer-sized powders of BaCO3 and TiO2. Microstructure and phase composition are reported and discussed in connection with optical and photocatalytic properties. Color of the sprayed coating is different from sintered BaTiO3. X-ray diffraction shows certain content of amorphous fraction in the coating. Hydrogen content in the coating was found to be higher then in the sintered bulk.
