AbstractIn this work , barium titanate ( BaTiO3) ceramic was prepared using two systems (BaO- TiO2) , (Ba acetate-TiO2) by solid state reaction method . X-ray diffraction patterns showed that the ( BaO- TiO2) prepared BaTiO3 ceramic was a good growth when it calcimine at 1200 C for 2 hr . But (Ba acetate –TiO2) prepared BaTiO3 was a bad growth at 1200 C ,hence it requires calcimine temperature above 1200 C Using optical microscopy, the particle size and shape for each powder has been noted .
The results of dielectric strength measurements showed that the dielectric strength strongly depend on the temperature , in which the dielectric strength decrease as temperature increase with more significant above 120 C .
