| Abstract: | The paper stresses to study the process and parameters of preparation in the synthisis of high pure and ul-trafine BaTiO3 powders by Ti(OnBu)4-Ba(OAc)2 hydrolysis. Characters of BaTiO3 powders synthesised in differential condi-tions are tested and analysed by mean of TG-DAT, XRD, TEM,SAXS and ICP-AES. Their laws are discovered. The BaTiO2 powders with Purity of 99. 80wt% and surface area of 68m2/g .primary particles of a'-)erage diameter of 46. 7nm sec-ondary particles (laggregates) of diameter ranging between 20 are prepared by the method. |
