Three commercially available barium titanate powders were employed in this study. These three materials were fabricated into discs suitable for electrical measurements. Several steps in the fabrication process were varied in an attempt to determine optimum conditions for obtaining the best electrical properties for thc given material. Calcination, particle size, grinding technique, binder addition, forming method, forming pressure, maturing temperature, firing cycle, cooling cycle, and setter materials were the variables investigated. The effect of these variables on dielectric constant, planar coupling coefficient, density, and firing shrinkage of barium titanate is reported. (auth)
