Le grenat de gadolinium-gallium (généralem … Le grenat de gadolinium-gallium (généralement désigné par GGG, pour gadolinium gallium garnet) est un grenat synthétique généralement incolore de formule chimique Gd3Ga5O12 possédant de bonnes propriétés optiques, mécaniques et thermiques. Il cristallise dans le système cubique et possède une masse volumique de 7,08 g·cm-3 ainsi qu'une dureté variant selon les auteurs de 6.5 à 7.5 sur l'échelle de Mohs. Il possède diverses applications optiques et magnéto-optiques et peut être utilisé comme substrat pour la croissance de couches de grenat de fer et d'yttrium par épitaxie.e grenat de fer et d'yttrium par épitaxie.
, Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) … Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) is a synthetic crystalline material of the garnet group, with good mechanical, thermal, and optical properties. It is typically colorless. It has a cubic lattice, a density of 7.08 g/cm3 and its Mohs hardness is variously noted as 6.5 and 7.5. Its crystals are produced with the Czochralski method. During production, various dopants can be added for colour modification. The material is also used in fabrication of various optical components and as a substrate material for magneto–optical films (magnetic bubble memory). It also finds use in jewelry as a diamond simulant. GGG can also be used as a seed substrate for the growth of other garnets such as yttrium iron garnet.other garnets such as yttrium iron garnet.
