MgAl2O4 Superconducting Thin Monocrystalline Substrate 10x10x0.5mmt 1sp/2sp
Magnesium aluminate (spinel) single crystals are widely […]
Magnesium aluminate (spinel) single crystals are widely used in acoustic and microwave devices and fast IC epitaxial substrate. Found that it was good while group III-V nitride substrate of the device. MgAl2O4 crystal because of its crystal structure is difficult to maintain and difficult to grow, after several years of efforts, the Branch crystal company can provide the best quality in the world the size of MgAl2O4 crystals.
