PRODUCT:  MgO


Introduction:

Magnesium oxide (MgO style) is an excellent single crystal substrate and widely used in the production of  ferroelectric thin films, magnetic thin films, thin-film photovoltaics and high temperature superconducting thin films, because it in the microwave band dielectric constant and loss are very small, and it can get a large area of the substrate (2 inches in diameter and larger), makes it to be one of the important high temperature superconducting thin film single crystal substrate. It can be used to make high temperature superconducting microwave filters and other devices for mobile communication equipment.
