Microstructural studies of strontium titanate ceramic pressed at varying pressure

The purpose of this study is to fabricate the Strontium Titanate (SrTiO3) ceramics by using the High Energy Ball Milling Method (HEBM) for 9 hours at varying pressure between 60 MPa to 160 MPa at an interval 20 MPa. The samples were sintered at 1100 °C. The microstructures and morphology the samples...
