Al2O3 (Aluminum Oxide, Alumina) - Digitalfire

However the Al 2 O 3 in alumina hydrate or calcined alumina is a crystalline solid (these materials are very refractory and sintered into a multitude of hi-tech ceramic products). Thus, alumina, as a material, is not a good source of Al 2 O 3 to glaze melts, it does not readily melt and yield the oxides.
