摘要：

The microstructure of SrO-doped CaTiO3 ceramics was investigated using transmission electron microscopy (TEM). It was found that the excess SrO forms insertion planar precipitates which are coherently intergrown with the CaTiO3 crystal. Two different types of SrO intergrowth were observed: (101)/(001)SrO/(020) and (020)/(001)SrO/(020). The phenomenon is similar to that observed by Ruddlesden and Popper in the system SrTiO3-SrO. © 1993 Academic Press, Inc.
