In this study, the zeolitic tuffs having clinoptilolite obtained from Bigadic region of western of Anatolia, Turkey were investigated
as regards to whether it is possible to be transformed into amorphous phase from them. At first, the zeolite tuffs rich in
clinoptilolite were characterized using XRD, DTA, TG, DSC, and FTIR standard methods. All the samples were heated at 110 °C
for 2 h and then were expanded within 5 min between the temperatures 1200 and 1400 °C. In addition, porosity and density were
determined. The resistance values of all the samples were measured in acidic and basic media. These samples were also analyzed.
As a result of this study, zeolitic tuffs in clinoptilolite were transformed into amorphous phase, and especially in chemical
industry were found convenient.
