摘要：

Polycrystalline BaTiO3 bulk ceramics with a preferred <111> or <100> orientation were fabricated by the reactive templated grain growth method. Green compacts were made by tape-casting of slurry containing plate-like Ba6Ti17O40 or Bi4Ti3O12 template particles and BaCO3 Powder. Single phase BaTiO3 was obtained by calcining the green compacts containing Ba6Ti17O40 and BaCO3 in air and those containing Bi4Ti3O12 and BaCO3 in vacuum. The sintered compacts with a significant. grain orientation were obtained, but they contained large pores. The addition of BaTiO3 with small particle size as a filler increased the sintered density without, reducing the degree of grain orientation.
