JDCD08-001-007 6inch C-Plane Sapphire Substrate Wafer
Ruby and sapphires are both made of corundum (aluminium oxide - Al2O3). Corundum is one of the hardest known natural substance after diamond. In addition, because corundum is so hard and resistant to weathering, it can also be found in sedimentary deposits and sedimentary rocks.
Sapphire ranks 9 on the Mohs hardness scale. Corundum is stable under normal wearing conditions, which means it's resistant to the effects of heat, light, and common chemicals.
