Product Description

DIA 4 Inch SGGG Wafer YIG Film Substrates

SGGG single crystal, e.g. substituted gadolinium gallium garnet is grown by Czochralski method .

SGGG crystals with calcium, magnesium and zirconium as substituting ions, which are used as the substrates for the growth of bismuth-substituted iron garnet epitaxial films, which is good material for YIG,and BIG flim 

Our Company:

Crystro has perfect automatic production machine, the current products are mainly concentrated in the YAG, TGG, TSAG,GGG ,LGS,Ce:GAGG ,Ce:YAG and Ce: LuYAG crystals.

We also established a crystal research center and developed different kinds of crystals. Keep providing technical support and training for new applications and product development staffs.
