There are many species of zeolites, such as Analcime, Chabazite, Clinoptilolite, Faujasite, Ferrierite, Heulandite, Laumontite, Mordenite.
After the analyses, the soil minerals found were: quartz, calcite, sanidine, albite, nontronite, muscovite, montmorillonite, hematite, faujasite, dolomite, microcline, anorthite, anorthoclase, clinochlore and epidote.
Figure 5c shows spheroidal morphologies and relict flaky crystals of the starting material, as well as dodecahedral crystals of faujasite, displaying a typical cubic (octahedral) symmetry and simple twinning, from which flaky aggregates grow.
Synthesis of faujasite from coal fly ashes under smooth temperature and pressure conditions: a cost saving process.
Our data indicated the formation of-phillipsite (PDF 000-51-1497), sodalite (PDF 010-88-1190) and faujasite (PDF 000-39-1380).
The sorbents were obtained by ion exchanging faujasite type zeolites with [Cu.
Spence (1920) noted the presence of stilbite and heulandite in fluorapatite-phlogopite skarn deposits, and Hoffman (1901) reported faujasite from the Daisy mine, Papineau Co.
Thus, we used naturally occurring erionite and mordenite as well as an extensively studied synthetic zeolite based on faujasite (zeolite Y).
Fleming has also initiated several other research directions using the muon as a (radioactive) spin probe: [micro]+/Mu charge and spin exchange, chemiluminescence studies, hyperfine coupling constants and spin relaxation of Mu-radicals in the gas phase and in faujasite microcrystalline environments.

Six years ago, another group used X-ray spectroscopy to pinpoint the locations of metal ions bound to a zeolite called faujasite.
