Abstract

High resolution transmission electron microscopy (HRTEM) observations of the interphase interfaces in the directionally solidified eutectic (DSE) NiO-ZrO₂(CaO) are presented. The planar lamellar interfaces were observed to be extremely clean without any evidence of an interface phase. Characteristic line and/or step defects at the interface have been identified and analyzed. Chemical microanalysis using X-ray emission spectroscopy (XES) indicated clear partitioning of CaO to ZrO₂. The observations are discussed in view of the limited understanding of the structure and chemistry of interphase interfaces in oxide systems.
