Magnesium Oxide

Magnesium oxide targets are used in RF sputtering to create thin film dielectric layers and protective coatings in plasma displays and magnetic tunnel junctions.

MgO is utilized as a high-refractive index material for multilayer optical coatings and UV-reflective films due to its wide bandgap and transparency.

Magnesium oxide is used as an evaporation source for depositing thin films in electronic and optical applications, often requiring electron-beam evaporation.

Due to its extremely high melting point and chemical stability, MgO is a primary component in refractory bricks and crucibles for high-temperature metal processing.

MgO serves as a high-temperature insulator and structural material in heating elements and thermocouple sensors.
