Investigation of Chemical Durability Mechanisms in Fluoride Glasses.

Abstract

Aqueous corrosion mechanisms are investigated in heavy-mental fluoride glasses. The family of glasses based on the Zirconium tetrafluoride glass former is rapidly attacked by water which is either unbuffered or contains acidic components. However, these glasses resist corrosion by basic solutions. ThF4-based glasses exhibit a higher resistance. Comparisons are made between the 2 glass families; pH dependence of corrosion is analyzed and a corrosion model is presented.
