METHOD FOR SYNTHESIS OF SOLID SOLUTION POWDERS BaSrTiO Russian patent published in 2015 - IPC C01G23/00 C01F11/00 C04B35/468 C09C1/02 C09C1/36 

FIELD: chemistry.

SUBSTANCE: invention can be used in producing pigments for white paints and coatings, including thermal control coatings. Producing solid solution powders Ba_(1-x)Sr_xTiO₃ is ensured by mixing barium carbonate BaCO₃, strontium carbonate SrCO₃ and titanium dioxide TiO₂ powders in the required weight parts. The prepared mixture is heated. The mixed powders are heated sequentially: 2 hours at 800°C, then after cooling down, 2 hours at 1,200°C.

EFFECT: invention enables avoiding the high-temperature heating, compaction and disintegration in producing the solid solution powders Ba_(1-x)Sr_xTiO₃, increasing the yield.
