Popis: The effect of thermal annealing on the resistance of borosilicate systems to crystallization and the effect of this process on the hydrolytic stability of the materials were examined. The systems containing REE + TUE and Cs + Sr fractions were studied. For borobasalt matrices containing the REE + TUE fraction, annealing in the temperature rangte 400–600°C leads to an appreciable decrease in the leach rate in water. For the borobasalt system containing waste components of the Cs + Sr fraction, changes in the leach rate upon thermal annealing are not clearly observed up to the annealing temperature of 600°C.
