Mullite Formation in the Aluminium Fluoride–Silica System (AlF3–SiO2)

Abstract

THE role of mullite, the conditions and kinetics of its formation are among the main problems of ceramic theory. The equilibrium conditions of the alumina–silica system have been established1–3. Grofcsik and Vago4,5 have given an answer to the problems of kinetics on the basis of results obtained from their investigations carried out on silica gel and alumina. Several authors have dealt with the mineralization of mullite formation too6–8. The examination of the AlF3–SiO2 system suggests a way which may clear up the problem of possible mullite-formation mechanisms in ceramic products.
