BaTiO powder with small particle size and high tetragonality was synthesized by a sanding solid-state phase method with domestic submicron BaCO and TiO as raw materials. We also studied the effects of calcination temperature, heating rate and holding time on the average particle size and tetragonality of BaTiO. The results show that the reaction mechanism for the synthesis of BaTiO by solid phase reaction can be divided into two stages: when the calcination temperature is lower than 900℃, BaCO and TiO first form cubic phase BaTiO. When the calcination temperature rises to 900℃, the cubic phase BaTiO begins to transform into a tetragonal phase. Ultrafine BaTiO powder with a particle size of 180. 7 nm and a tetragonality (c/a) of 1.0086 is prepared at a calcination temperature of 900℃, a heating rate of 5℃/min, and a 5 h incubation. This work provides a good research idea for the preparation of high performance BaTiO powder used for ultra-thin MLCC.
