V. Saly et S. Kocalka, DIELECTRIC RESPONSE OF NATURAL CLINOPTILOLITE TYPE ZEOLITIC MATERIAL CONTAINING SILVER-IODIDE, Chemicke zvesti, 50(6), 1996, pp. 328-333
Natural zeolitic materials of the clinoptilolite type with regard to t
heir dielectric properties were investigated. The coated samples of th
e clinoptilolite (CT) and its product containing silver iodide (CTAgI)
in the form of the mixture of zeolitic powder and nonpolar paraffin o
il were used. Clinoptilolite creates an inclusion compound with AgI wh
ere AgI can enter into the tunnels and can be deposited on the surface
of clinoptilolite particles, too. Dielectric properties (complex perm
ittivity epsilon and loss factor tg delta) of the hydrated and dehydr
ated natural zeolite CT and its product CTAgI were investigated in the
frequency range from 10(1) Hz to 10(5) Hz and at the temperatures fro
m 20 degrees C to 70 degrees C. The conductivity of the CTAgI product
was measured in the temperature range from 70 degrees C to 300 degrees
C at the frequency 1 kHz, too.
