Substituted GGG (SGGG) EPI 1sp Single Crystal Substrates

SGGG single crystal, (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.

Substituted Gadolinium Gallium Garnet (SGGG) is used as substrates for liquid epitaxy. The lattice parameter of our crystals is well controlled and the surface polish finishing is of the highest quality, allowing a perfect epitaxy.

SGGG is used as substrates for liquid epitaxy.It's dedicated substrates for magneto-optical film.

Anhui Crystro participate in the kinds exhibitions every year: Laser World of Photonics Munich, Shanghai, Photonics West in San Francisco, CIOE in Shenzhen, etc.
