Calcined mixtures of kaolin and alumina were prepared by grinding for different lengths of time and firing the several grinds at different temperatures ranging from slightly above dehydration temperature of clay to 1700°C. The X‐ray diffraction patterns revealed several interesting points relative to the degree of combination of the oxides present.
