| Popis: | A polycrystalline BaTiO3 bulk ceramic with a preferred ‹111› orientation was fabricated by the reactive templated grain growth method. A green compact was made by tape-casting of slurry containing plate-like Ba5Ti17O40 template particles and BaCO3 powder. Single phase BaTiO3 was obtained by calcining the green compact at 1000°C. The calcined compacts were sintered between 1250 and 1400°C. The degree of orientation increased with an increase in the sintering temperature. Growth of ‹111›-oriented BaTiO3 grains originated from the Ba6Ti17O40 particles is responsible for the increase in the degree of orientation. |
