Dense, thin sheets of α‐alumina formed after solidification of powder compact surfaces which were melted using CO2 laser radiation. The microstructures and surface topographies varied with the depth of melt. Most significant was a zone of columnar grains oriented in the [661] direction which yielded smooth surfaces for intermediate depths.
