Zeolites are microporous aluminosilicate minerals such as analcime, chabazite, clinoptilolite, heulandite, natrolite, phillipsite, and stilbite.
Analcime was found in saline lakes and terrestrial sediments in warm, rather arid regions, frequently associated with phillipsite, chabazite and natrolite [19].
The results showed that synthesis products contained analcime, zeolite Na-Pl and phillipsite (Querol et al.
A synthetic zeolite Na-[P.sub.1] has similar pore structure to the natural zeolite phillipsite. Na-[P.sub.1] zeolite is classified as high silica zeolites where it has Si/Al ratio equal to or greater than about 3.
The micro X-ray diffraction analyses performed at ALS beamline 12.2.2 (also described in the Journal of the American Ceramic Society article) show the mineral structure of Al-tobermorite and phillipsite in the cementitious matrix of the ancient seawater mortar."
Geological Survey has reported natural zeolites' worldwide occurrence in the USA, Japan, Korea, Bulgaria, Czechoslovakia, Romania, Hungary, Russia, Yugoslavia, South Africa, Italy, Germany, Turkey and China, the latter having the greatest worldwide production Clinoptilolite, mordenite, heulandite, chabazite, phillipsite and laumontite are some of the more than 40 known natural zeolites occurring in reasonably high quantities and purity.
The neutralization of the solution (Figure 2a) is initially very rapid, with the pH increasing from4.94to 10.32 (hydroxysodalite), 10.41 (Na phillipsite) and 10.46 (K-chabazite) within 5 minutes.
The zeolite formation (phillipsite type) was detected by XRD and SEM-EDX in the tests with bentonite at 35 - 90[degrees]C and in the tests with montmorillonite at 90[degrees]C after 12 months or 12 weeks, respectively.
We think it's probably the 55 million square miles mentioned in this lengthy definition of red clay: A slowly accumulating abysmal deposit covering some 55,000,000 square miles of the deepest part of the ocean bottom and consisting of the insoluble residual material of volcanic and meteoritic or cosmic dust mingled with nodules of manganese oxide, crystals of the zeolite phillipsite, sharks' teeth, the siliceous tests of Radiolaria, and other resistant organic debris
