The main purpose of this work is the synthesis of faujasite zeolite using three different kinds of kaolin from the Amazon region, Brazil: two kaolin from the beneficiation process for paper coating and hard or flint kaolin, a non-processed kaoling from the mining site. Analysis of the reaction products of kaolin showed the formation of faujasite zeolite. Flint kaolin showed a lower potential with respect to zeolitization ratio Si/Al equal to 2, compared to processed kaolins, probably related to the iron present in the structure. New results show a complete change in the formation of faujasite, which turns to be the main mineralogical phase after iron removal. |
