Abstract
A series of BaTiO3 solid solutions were synthesized by sol-gel method during different aging time. The effect of aging time on the dielectric properties of BaTiO3 ceramics was discussed. A series of BaTiO3: x Eu2O3 and Ba0.9Sr0.1TiO3: xEu2O3 solid solutions were synthesized by sol-gel method and their properties were investigated. The ceramics obtained were of high dielectric constants at room temperature. The results indicated that the dielectric properties of BaTiO3 ceramics were improved by doping with Eu2O3. The doping of Sr2+ resulted in the decrease in Tc and the increase of dielectric constant. The dopant Eu3+ not only caused the decrease in Tc, but also caused the broadening of Curie peak.
