JIN Zong-lian,XU Hua-rui, ZHU Meng-qin GU Hong-chen (Institute of Technical Chemistry and Physics,East China University of Science and Technology,Shanghai,200237,China) [WT5”HZ]  
A new process for synthesing barium titanyl oxalate tetrahydrate-spray reaction were proposed on the basis of applying the principle of homogeneous precipitation in the droplets mini-reactor.The Ba/Ti ratio and harmful impurity of BaTiO 3 was analyzed by the methods of chemical analysis and X-fluorescence spectrum.The crystal structure,particle size and morphology of the BaTiO 3 were characterized by XRD,TEM,etc..The results showed that BaTiO 3 powder obtained from the process is in high purity,small particle and narrow size distribution.
