摘要

Formulas of natural zeolites are generally cumbersome and not easily comparable because of differences in their written form. A summary of the formulas normalized at n = 1 is given for aluminosilicate zeolites with the [(Si,Al)nO2n] frameworks. Novel volume parameters are proposed for the framework instead of the framework density (FD) and a zeolite as a whole, which are calculated as the effective volumes of a mean (Si, Al, O) atom and a mean atom of the compound. We show the efficiency of the comparative crystal chemical analysis of zeolites in a common scale with the use of unified characteristics.
