Abstract

MULLITE, first identified only fifty years ago, was quickly recognised to be an important industrial mineral. Its chemical composition was determined initially as 3Al2O3.2SiO2 on the basis of two chemical analyses1,2 and the observation that when a synthetic mixture of 3:2 composition was fired to temperatures just below the liquidus, no glass or corundum was observed1. Although more aluminium-rich mullites were found subsequently3, the 3:2 or “stoichiometric”4 composition remains the generally accepted one.
