ze·o·lite

(zē'ō-līt),
A naturally occurring hydrated sodium aluminum silicate, Na2O·Al2O3·(SiO2)x·(H2O)x, used for softening of hard water by exchanging its Na+ for the Ca2+ of the water; thus zeolite is an ion exchanger. Some synthetic ion exchangers are termed synthetic zeolites, although no chemical relationship exists.

zeolite

(zē′ŏ-līt″) [Gr. zein, to boil + -lite]
A mineral containing aluminum and silica used to adsorb liquids and stop bleeding.

The employment of the modified zeolitic rock allows a reduction in zinc phosphate content, with a consequent savings.
This has been very effective for the study of zeolitic materials, since optimum resolution is needed at relatively low Q values, as opposed to dense-phase materials.
Aluminosilicate zeolitic materials are constructed of tetrahedral [[AlO.
Every month or so he would drive his jeep to any operating quarries where he had learned that zeolitic minerals were turning up.
Moreover, this approach yielded previously unknown versions of zeolitic imidazolate frameworks (ZIFs), which are topologically similar to zeolites.
Aluminosilicate gel (N-A-S-H) is obtained as main product and, in some cases, short-range order zeolitic phases are generated as secondary product (Duxson et al.

The topics include novel approaches to statistical learning in materials science, data dimensionality reduction in materials science, towards the rational design of sensing materials from combinatorial experiments, high-performance computing for accelerated zeolitic materials modeling, and using multivariate analysis to answer questions concerning the conservation of artworks and cultural heritage materials.
It is essential to note that application of high temperatures for activation of such clay catalysts as palygorskite, bentonite and kaolinite causes not only the loss of the hygroscopic, zeolitic and crystal waters, C[O.
The zeolitic material was repeatedly washed with deionized water to remove excess sodium hydroxide until the washing water had pH ~ 10, then it was dried at 50[degrees]C for 12 h [30].
And demand for zeolitic catalysts used in the system is also expected to expand rapidly.
Several authors have reported the synthesis of kaolinite- and the metakaolinite-based zeolitic materials (e.
