The Precipitation of Fluorides in Glassy Systems
JSGT 1952 V36 T266-T269
The fluorides which are precipitated on cooling various fluorine-containing silicate melts have been identified. In melts containing ZnO, no ZnF2 is precipitated despite the marked increase of opalescence over similar melts containing CaO. While NaF is freely precipitated from melts containing Na2O, it appears that KF is less readily formed in melts containing K2O.
