Resource type: Image
Description: The image shows the classic angular shape of corundum (alumina) grains formed in a liquid medium. The intergranular regions are dark and contain the aluminosilicate glass left from the cooled liquid. This liquid will soften at high temperature and limit the maximum use temperature of the ceramic.
