The effect of temperature on the dielectric strength of BaTiO3 ceramic

الملخص EN

In this work, barium titan ate (BaTiO3) ceramic was prepared using two systems (BuO-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.
