The paper discusses the features of RESG which influence the crystal growth. RESG are nonstoichiometric compounds with complex scandium isomorphism which results in substantial variations of the crystallized composition. The presence of chrormuim ions in RESG strongly increases the absorption capability of the medium and leads to the rise of interface instability during the growth. The principle differences between ScGa‐ and ScAl‐garnets concerning crystallization features are considered.
