BaTiO₃ is known to be an environmentally friendly electronic material with a phase transition temperature that can be controlled through the substitution of an appropriate additive. Physical changes of grain growth in Ba<SUB>0.9</SUB>Sb<SUB>0.1</SUB>TiO₃ were analyzed by adding a small amount of antimony to pure BaTiO₃. The Ba<SUB>0.9</SUB>Sb<SUB>0.1</SUB>TiO₃ solid solution with antimony substitution was prepared under various calcination and sintering conditions. The optimal conditions for sintering were confirmed and the grain growth process was clearly understood. As a result, the relationship between the dielectric properties and the polycrystalline structure of Ba<SUB>0.9</SUB>Sb<SUB>0.1</SUB>TiO₃ substituted with antimony was confirmed. The maximum dielectric constant of the Ba<SUB>0.9</SUB>Sb<SUB>0.1</SUB>TiO₃ solid solution was found to exceed about 5500 and the dielectric constant at room temperature reached nearly 4000. The transition temperature of Ba<SUB>0.9</SUB>Sb<SUB>0.1</SUB>TiO₃ was shifted closer to room temperature than that of pure BaTiO₃. Unlike the phase transition behavior of pure BaTiO₃, the dielectric constant curve, which is a function of temperature for all samples, showed a very gradual change.
