Popis: The consequences of using hydrated raw materials for the preparation of ZBLAN glass were qualitatively assessed in terms of effect upon 1) general appearance, 2) hydroxyl content, 3) oxide content and 4) presence of inclusions. Glasses were prepared using ZrF4·H2O and sublimed ZrF4 and dry N2 and dry N2 + CCl4 atmospheres. The resulting glasses were examined with the aid of IR spectroscopy and optical microscopy. It was found that the use of hydrated raw materials did not significantly enhance the OH- or O--concentration of the glass, but did produce a degradation of glass quality.
