MgO single crystal as the dielectric constant and loss microwave band is very small, and can obtain a large area substrate (diameter of 2 inches and larger), it is currently an important industrial HTS thin monocrystalline substrate world.
Ceramic substrate made of 96% alumina, is mainly used in electrical applications.Ceramic fixture made of 95% or 99%, alumina, is mainly used in welding parts of mechanical equipment, or insulation parts needing fixture,
