Magnesium aluminate (MgAl2O4) single crystals are widely used in sonic and microwave devices and in the production of epitaxial MgAl2O4 substrates of III-V nitride devices. The MgAl2O4 crystal was previously difficult to grow because it is difficult to maintain its single crystal structure, but at present we have been able to provide high quality ang 2 inch diameter MgAl2O4 crystals.
