EPI Polish GGG Single Crystal Substrates
Gallium Gadolinium Garnet (Gd3Ga5O12 or GGG) single crystal subatrates is used as substrates for liquid epitaxy growth of YIG or BIG film.
GGG substrates is dedicated substrates for magneto optical film.
GGG has been successfully applied in the magnetic refrigeration industry in the temperature zone below 20 k for market HeII flow and helium-nitrogen liquefaction pre-stage refrigeration.
Crystro's GGG has low optical lossed(<0.1%/cm),high thermal conductivity(7.4W m-1K-1),High laser damage threshold(>1GW/cm2)
