Formation of Barium Strontium Titanate Powder by Solid State Reaction using Different Calcination Temperatures
Abstract
The unique electrical properties of large permittivity in Barium Strontium Titanate have been widely used to make capacitors; it can be produced by solid state reaction. In this study, the mixture of Barium Carbonate, Strontium Carbonate and Titanium Dioxide was calcined at 500°C, 1000°C, 1100°C, 1150°C, 1200°C, 1250°C and 1300°C. The results of the phases change in each stage were investigated via X-Ray Diffraction. The results show that the formation of Barium Strontium Titanate started at 1100°C with the presence of other phases. The mixture is fully reacted to form Barium Strontium Titanate at 1150°C. Only Barium Strontium Titanate was formed as the calcination temperature was set higher.
