| Abstract: | The technology for fine-grained BaTiO3-based ceramics of high capacity and good thermal stabilization is researched, including pro-treating, mixture and sintering. BaTiO3 obtained by co-precipitation formed tetragonal phase over 1 000℃ in heat-treating. Better dielectric properties of the system can be achieved by a strict control of sintering temperature, keeping time and ball-mill time. |
