The formation of cristobalite from the diatomaceous clay moler was investigated ex situ in the temperature range 800°–1200°C using powder X‐ray diffractometry and in situ in the temperature range 1000°–1100°C using the same method. Profile analysis of the powder patterns was used to determine the quantity of β‐cristobalite in the in situ experiments and the quantity of α‐cristobalite in the ex situ experiments.
