Abstract
In this study, it was found that BaO-B2O3-SiO 2 glass powders with fine particle sizes and spherical shapes improved the sintering characteristics of nanosized BaTiO3 powders. The mean sizes of the prepared glass powders and BaTiO3 powders were 940 nm and 110 nm, respectively. The densities of BaTiO3 pellets containing 0, 1, 3, and 5 mass% of a glass additive were 4.2, 5.2, 5.5 and 5.7 gcm-3, respectively, at a sintering temperature of 900°C. The densities of BaTiO3 pellets sintered at 900°C and containing 5 mass% of the glass additive were similar to that of the pellet sintered at 1280°C and containing no glass additive. Dielectric constants of pellets containing 5 mass% of the glass additive and of pellets containing no glass additive were 1599 and 469, respectively, at a sintering temperature of 900°C. Dielectric constants of pellets containing 1 mass% of the glass additive increased from 602 to 4109 when the sintering temperature was increased from 800 to 1200°C.
