| Abstract: | Nanosized BaTiO3 powders were prepared in the laboratory by HGRP from hydrolyzed TiCl4 and hydrated BaCl2·2H2O. And in this process NaOH acted as a precipitant. HGRP combined the advantages of direct-reactive precipitation and high gravity reactor. Powders obtained by this technology were studied by TEM, BET, XRD, AES-ICP and chemical analysis. The results showed that the nano-powders had a size of about 30～70nm and was of cubic perovskite structure. The powders had Ba/Ti molar ratio of (1.000±0.005) and high purity. |
