Kaolin was irradiated with 0.67 meV gamma-rays from a Cs137 source. Irradiation dosages of more than 1019 eV/g retarded mullite formation whereas smaller dosages appeared to have enhanced mullite formation slightly. It appears that preferentially oriented mullite formation from kaolinite is energetically favored and is adversely affected by radiation-produced nb/3 shifting of the Al ions. A possible mechanism for the effects of the radiation on mullite formation is suggested.
