Ceramic Sample of tin doped pure barium titanate prepared by solid-state reaction at
a sintering temperature of 1350˚C for 3.5h. The electrical properties of ceramic BaTi1-
xSnxO3 studied for the ratios (x= 0, 0.05, 0.07, 0.1, 0.12, 0.15, 0.17), as
a function of
temperature from 0˚C to 170˚C at 1kHz. The maximum value of the dielectric constant
reached to έ=6568 for the content x=0.1 at the temperature Tc=50˚C. The phase transition
for barium titanate was of the first type with γ=1.07. The degree of the transition changed
by increase the ratio of added tin. Where the maximum value of transition degree γ=1.46 at
the ratio x=0.15. Curie constant decreases with increasing ratios of tin added to the ceramic
samples.
