Magnesium Oxide, Powder, 99.995%, -1250 mesh (2.8 mic aps) approx

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.
