Abstract

The crystallizing phases from a BaZn YbTh fluoride glass were a BaYbTh fluoride, ZnF2, and YbF3, as identified with x-ray diffraction and composition-enhanced scanning electron microscopy. Blocky BaYbTh fluoride crystallizes first, at about 450 °C, and ZnF2 excluded from this phase crystallizes at its surfaces. At higher temperatures the BaYbTh fluoride phase decomposes partially to BaThF6 and YbF3 phases. The kinetics and temperatures of crystallization were also followed with differential scanning calorimetry.
