| Abstract: | In this paper, two different homogeneous precipitation processes under acidity and basicity conditions are designed and compared. With the aid of various means of analysis , including chemical analysis of XRD, SEM, TG-DTA and atom emission spectrum etc, comparisions in the following aspects have been done, such as the composition, purity, degree of fineness and state of dispersion for BaTiO 3 power. It is shown that properties of BaTiO 3 ultrafine powder by acidity technology are superior to those by basicity technology. |
