Synthetic sapphire is a single crystal form of corundum, aka, pure single crystal aluminum oxide, Al2O3. The combination of its unique properties make sapphire a preferred material for extreme mechanical, chemical & optical applications. Unlike glass, sapphire cannot be molded. Sapphire can be grown into near net shapes such as tubes and rod, then ground and polished.
