Abstract：
 A process for preparing the tetragonal nanoparticles of barium titanate includes such steps as preparing solution of titanium nitrate oxide, proportionally mixing it with the aqueous solution of barium nitrate, citric acid and ammonium nitrate, heating for becoming colloid by evaporation, and burning. Its advantage are high purity, easily controlled granularity, and low cost.
