Abstract
. The influence of alkalies, alkaline earth oxides, Fe20 3 and Ti02 on mullitiza-
11011 of a pure kaolinitic clay was studied by quantitative X-ray diffraction measurements,
using !-alumina as the internal standard. Earlier investigations indicate
that the yield of mul/ite varies, within wide limits, with the coiiCentration of the
mineralizers. The results show that the amounts in which these impurities are
generally present in clays have profound influence on the process of mullitization.
