Product Details
Description
MgO single crystal as the dielectric constant and loss microwave band is very small, and can obtain a large area substrate (diameter of 2 inches and larger), it is currently an important industrial HTS thin monocrystalline substrate world.MgO is an excellent single crystal substrate for thin films of Ferro magnetic, Photo-electronic and high Tc superconductor materials.
