The spinel phase formed on the thermal reaction of kaolin group minerals was characterized by X‐ray quantitative analysis, lattice constant determination, and chemical analysis by analytical TEM. The spinel phase was determined to be nearly γ‐Al 2 O 3 with ∼8 wt% of SiO 2 , significantly less than previously reported.
