Faujasite is a mineral group in the zeolite family of silicate group consists of faujasiteNa, faujasiteMg and faujasiteCa. They all share the same basic formula: (Na 2,Ca,Mg) [Al 7 Si 17 O 48]·32(H 2 O) by varying the amounts of sodium, magnesium and calcium. It occurs as a rare mineral in several locations worldwide and is also synthesized industrially.
Sodium silicate was supplied by Fluka Chemia, and sodium hydroxide was supplied from BDH (England). Preparations of zeolite 13X The preparation of sodium type zeolite 13X was carried out by the addition of (9%wt) sodium hydroxide solution to the metakaolin and sodium trisilicate mixture.

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.
Nov 01, 2013· The XRD spectrum of CaA zeolite using leached sodium aluminate from kaolin and sodium silicate through the conventional method at 75 °C, that was briefly referred to in Section along with the standard XRD spectrum of 5A zeolite used as a reference are shown in Fig. 2(a) and (b), respectively. One can see that major peaks in both XRD patterns are similar, and there is only some ...

sodium silicate both used from the total binder weight), while nanokaolin was added in the ratio from 0 up to 9% from the total dry weight and replaced the used metakaolin. the properties of the produced geopolymer bricks have been studied through measurement of compressive
The sodium silicate, however, is the hightemperature adhesive; the kaolin serves simply as a compatible hightemperature coloring agent. Some of these repair compounds also contain glass fibres to enhance their gapfilling abilities and reduce brittleness. Sodium silicate can be used to fill gaps within the head gasket.
