Effect of sintering temperatures on the microstructure and dielectric properties of SrTiO3

Conventional solid state reaction method is a common and effective way to fabricate modern ceramics. For ceramic processing, sintering is an important factor that affects the microstructure evolution, thus optimizing its natural abilities. In this work, Strontium Titanate (ST) ceramic samples sinter...
