MgO
MgO is widely used for magnet film, semiconductive film, Photo-electronic and high Tc
superconductor materials. MgO crystal is possible to get large size (larger than 2 inch) and has low dielectric loss in microwave band, so it is an important material for high Tc superconductive microwave devices in the mobile communication.
We can offer vaporize
the MgO crystal Block with PDP displayer as well.
