Magnesium oxide (MgO)

Magnesium oxide (MgO)

Introduction:

Magnesium oxide (MgO) single crystal wafers are widely used in film technology fields, such as production of magnetic films, semiconductor films, optical films and high temperature superconducting films. It is an important high-temperature superconducting thin film wafer which is currently industrialized. It can be used to fabricate high-temperature superconducting microwave filters and other devices required for mobile communication equipment.
