Conductivity and Dielectric Relaxation

The zeolites are described by the idealised formula M~/',[(AlO2),(SiO2),]. H2O where y> x and n is the charge of the cation M, and are characterized by the atomic ratios [O/(Al+ Si)] = 2 and [A1203/(Na2, Kz, Ca, Sr, Ba)0] = 1. They were recognised as a new group in mineralogy over 200years ago with the first member, stilbite, to be dis
