Antimony Doping Effect on Barium Strontium Titanate
Doping effect of Sb on Pb-free barium strontium titanate was investigated.The Sb doped (Ba,Sr)TiO3 ceramics were prepared by solid reactions in 1473-1623 K by employing 0~1.2 wt% Sb2O5 as main additives.Density changes with sintering temperature were determined.The morphology and microstructure of the Sb doping samples were analyzed by SEM.The dielectric properties such as permittivity and dielectric loss were measured.It was found that addition of Sb benefited to low temperature high density sintering process.When the addition amount of Sb2O5 was about 0.6 wt%,the dielectric loss of (Ba,Sr)TiO3 was decreased from 1.9% to about 0.4% while the dielectric constant was kept over 2000.Possible mechanism of the improvement by Sb addition was discussed too.
