Optical and magneto-optical properties of MgO transparent ceramics

Abstract

The transparent MgO sample was obtained by the arc plasma melting procedure using micro-sized powder. The structure of the sample was examined using X-ray diffraction. The transmittance of MgO was close to 75% in the wavelenght range from 430 to 1100 nm. The value of the optical angle of polarization rotation in transparent MgO has been measured at energy from 1.5 eV to 3.1 eV. The band gap energy determined from Tauc relation was estimated as 3.94 eV. The magnesium oxide transparent ceramics have a potential to be applied in high temperature furnaces.
