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.Acesso AbertoSínteseZeólita faujasitaCaulimRecursos mineraisArtigo de Periódico
