Description
The paper deals with the solubility of (YSmLuCa)3(FeGe)5O12 garnet in PbO-B2O3 flux. An anionic model explaining the effect of B2O3 on the solubility of rare earth garnet is suggested. This model is based on the assumption that PbO in the melted mixture of PbO, B2O3, Fe2O3, R2O3, CaO, GeO2 dissociates into Pb2+ and O2-. The oxygen anions react with the other oxides under the formation of BO33-, FeO33-, RO69-, CaO22- and GeO32- anions, until the equilibrium is established. The garnet is dissociated into the anions mentioned above. The validity of the model is verified by an agreement of the experimentally determined saturation temperatures of the melts for LPE of garnet layers with the Arrhenius-type expression of the solubility product of the garnet.
