Mechanochemical synthesis of CaTiO3 powders: Microstructure and surface morphology

Abstract

Calcium titanate (CT) is a material that is similar to hydroxyapatite in biological properties. In this report, CT powders was prepared by using high energy planetary ball mill and to determine their phases distribution, microstructure and surface morphology as an effect of milling duration was characterized by XRD, SEM, and BET analysis. As results, XRD, SEM and BET analysis indicate that all the peaks were the CaTiO3 powders in regular shape and uniformly distributed size of 2 µm in 32 h. Finally, it can be concluded that with increasing the milling time has significantly influenced and reduced CaTiO3 crystalline powders after calcinations.
