Abstrakty
Praca dotyczy analizy rozpuszczalności kryształów Y3Al5O12 (YAG) w stopionej mieszaninie PbO-B2O3. Analizę przeprowadzono wykorzystując przedstawiony przez van Erk'a model, w którym założono, że rozpuszczona faza granatu tworzy z rozpuszczalnikiem PbO-B2O3 ciecz jonową. Określono zależności między iloczynem rozpuszczalności YAG bez domieszek oraz domieszkowanego jonami ziem rzadkich i galu a temperaturą nasycenia roztworu wysokotemperaturowego, z którego zachodziła epitaksja warstw YAG. Z wyznaczonych doświadczalnie zależności określono wartość entalpii rozpuszczania kryształów YAG.
This work is devoted to the analysis of the solubility of Y3Al5O12 crystals in a molten mixture of PbO-B2O3. The analysis was performed using the model proposed by Van Erk, which assumed that the dissolved garnet phase formed an ionic fluid with PbO-B2O3. The relation between the solubility product of YAG substituted by rare earth or gallium ions and non-substituted YAG and the saturation temperature of a high-temperature solution suitable for the epitaxial growth of YAG layers was determined. The value of the solution enthalpy of the YAG phase was estimated from this empirical relation.
