Abstract
The formation of cristobalite from the diatomaceous clay moler was investig ated ex situ in the temperature range 800 degrees -1200 degreesC using powd er X-ray diffractometry and in situ in the temperature range 1000 degrees - 1100 degreesC using the same method. Profile analysis of the powder pattern s was used to determine the quantity of beta -cristobalite in the in situ e xperiments and the quantity of alpha -cristobalite in the ex situ experimen ts.
