Abstract:
Commercial hydrothermally synthesized BaTiO3 powder with a cubic structure was annealed in a temperature range of ~900 ℃, and the cubic-tetragonal structure transition and microstructure evolution of the powder were investigated in relation to the sintering processes. The BaTiO3 powder used had a cubic structure below an annealing temperature of 900 ℃ and a tetragonal structure above 900 ℃. The pre-annealed powders with a cubic structure were transformed into powders with a tetragonal structure by sintering above 900 ℃, irrespective of the environment.
