Structure characterization and surface morphology of low sintering temperature synthesized calcium titanate ceramics

The purpose of this study is to investigate the effects of calcination temperature on the structure and surface morphology of calcium titanate (CaTiO3) ceramics. The structure and composition of pre-sintered CaTiO3 powder and sintered CaTiO3 ceramic samples were analyzed by x-ray diffraction (XRD)....
