Notes:
Microstructure and dielectric properties of Ba0.62Sr0.38TiO3 ceramics doped with x mol%(x=0.2~0.6) Y2O3 were investigated. SEM showed that Y3+ can accelerate growth of the grains at first,then turn to inhabit growth of the grains with further addition of Y3+ above 0.8mol%. The experimentalresults showed that the dielectric constants were improved with the additive amount of Y3+ increasing, ifthe amount of Y3+ increased continuously, the dielectric constants will drop, whereas the dielectric lossesof the samples descended rapidly in the beginning, then went up obviously with further addition of Y3+above 1.0mol%, the optimal dielectric constant and dielectric loss could reach 6700 and 0.0015 in theroom temperature, respectively
