Abstract
The width of the crystallization regions of the oxyborate Na2Al2O(BO3)2 and the supersaturation degree of its solutions in different high-temperature solvents of the system Na2O-B2O3 have been determined. On the basis of comparison, the most suitable solvent for the growth of single crystals of this oxyborate has been found to be NaBO2. Studies have been performed on the solubility of Na2Al2O(BO3)2 in this solvent and the dependences of the viscosity and density of the solutions on the temperature and concentration of the oxyborate present in them. On the basis of the data obtained, a composition of the initial high-temperature solution for the growth of Na2Al2O(BO3)2 single crystals is proposed. The validity of this choice has been demonstrated by the growth of a single crystal on a seed using the top seeded solution growth (TSSG) technique and slow cooling of the solution. Recommendations have been made concerning the improvement of the growth process with a view to obtaining better quality crystals.
