Magnesium Oxide Single Crystal or MgO is an excellent single crystal substrate for thin films of Ferro magnetic,Photo-electronic and high Tc superconductor
materials. Red Optronics uses a special arc melting method to grow high purity MgO crystal in sizes up to
2"x2"x1" and employs CMP method to prepare high quality substrates with atomic level smoothness.
