HYDROTHERMAL SYNTHESIS OF SODALITE FROM BAUXITE WASHING CLAY AND ITS TRANSFORMATION INTO BETA-HEXACELSIAN-TYPE MATERIAL
In this work, b-hexacelsian (BaAl2Si2O8) type material was successfully obtained from the bauxite washing clay (BWC) from Amazon Region (Brazil), which was converted into zeolitic material type Na-sodalite. The route involved cation exchange of zeolite with Ba2+ ions, its subsequent thermal decomposition to form an amorphous barium aluminosilicate material from which b-hexacelsian recrystallized at higher temperatures (above 900º C)
