Texture development by templated grain growth in liquid-phase-sintered α-alumina

摘要

The distribution and orientation of platelet-shaped particles of α-alumina in a fine-grained alumina matrix is shown to template texture development via anisotropic grain growth. The textured microstructure ranges from 4 wt/100 oriented Platelet particles in calcined samples to nearly 100/100 ori- Ented α-Al_2O_3 grains after sintering at 1400 deg C.
