Abstract This paper presents the results of synthesis and characterization of calcium 0doped nanocrystalline barium titanate powder with different concentration of doped elements ((Ba1-xCax) TiO3, were x 0; 0.02; 0.06; 0.1; 0.16; 0.2), produced by oxalate route. Calcium additives were added on the surface the samples of semidecomposed barium titanil oxalate. For synthesis were used simultaneously decomposition of unstable barium, titanium compositions and calcium salts. The semidecomposed barium titanil oxalate and doped barium titanate characterization carried out by specific surface area measurements, TEM, X-Ray. It is experimentally shown that Са2+ introduction reduces lattice parameter for samples that related with replacement of barium by calcium. Solubility of calcium in barium titanate nanopowders increase from 10 at % up to 16 at %. The second phase appears at 20 at %.
