Surface tension of a titanium-containing oxide–fluoride melt calculated by the polymer theory

Abstract

The surface tension of an aluminum–calcium oxide–fluoride melt is calculated using the polymer theory. It is shown that, at 15 mol % titanium oxide in the melt, aluminum–fluorine–oxygen complexes mainly form. When the titanium oxide content increases further, these complexes disappear and are partly replaced by titanium–oxygen TiO₄^4- and Ti₂O₇^6- anions and titanium–fluorine–oxygen groups.
