https://www.cryscore.com/what-is-sapphire-ingot-and-its-application.html Sapphire ingots are aluminum oxide crystals used to produce sapphire substrates. The application of the sapphire ingots is the application of sapphire. As long as we know the performance of sapphire, we can know the application of sapphire ingots. Sapphire has a hexagonal lattice structure, and many properties are determined by its crystal orientation. Through the epitaxial film growth, different crystal orientations will show different lattice matching with the target material. Sapphire has a certain birefringence, and a special crystal axis is used in some optical fields.
