Texture Formed by Platelet Alignment in Ceramic Platelet Ceramic Matrix Composites

Abstract

3 mol% yttria stabilized zirconia matrix has been incorporated with 10 wt% single crystal α ‐alumina platelets to enhance the mechanical reliability. The composites have been produced by different forming techniques, namely, slip casting, tape casting, and injection moulding followed by pressureless sintering. Relative density ∼99% has been obtained. Alignment of the platelets in the material was analyzed by processing the images taken from scanning electron microscopy. Strong texture was formed by the alignment of platelet. Mechanical properties of the composites were evaluated, and co‐related to the alignment of the platelets.
