Abstract
In this study, high purity fine BaTiO3 powders were prepared by SHS (Self-propagating High-temperature Synthesis). We would examinate the study of sintering properties and characteristics as a function of temperature with various additives (binder, sintering agent). In separately binder addition, the green and sintered density of specimen were increased as binder content increases. The increased porosity resulted in fine grain size due to the inhibition of grain boundary moving. The Al2O3, TiO2 and MgO play a role of increasing dielectric constants at room temperature. These values were decreased at curie temperature. In case of SiO2, the Curie temperature was decreased. In this study, a high dielectric ceramic capacitor material with temperature stability was synthesized by using various additives.
