natural zeolites utilization
Natural zeolites
Natural zeolites. Zeolites are the group of minerals of volcanic-sedimentary origin, tectosilicate of aluminum of alkaline and earth metals. Nowadays more than 40 nature zeolites structural types are known, more diffused are clinoptilolite, limonite, flokite, chabazite.

Utilization of natural zeolites for solar energy storage
Utilizing 13X synthetic zeolite to store solar energy has been successful. In this paper, the storing solar energy principle of zeolites is discussed, the contrast study of natural zeolites to the 13X synthetic zeolite was made, and the conclusion showed that natural zeolites can be used as storing solar energy material completely instead of the 13x synthetic zeolite below 100°C.

Natural zeolites occur in mafic volcanic rocks as cavity fillings, probably as a result of deposition by fluids or vapours. In sedimentary rocks zeolites occur as alteration products of volcanic glass and serve as cementing material in detrital rocks; they also are found in chemical sedimentary rocks of marine origin. Extensive deposits of zeolites occur in all oceans.
