%X the aim of the present paper was to evaluate the reactivity of two diatomites samples, representative of two distinct geological environments (quiquel and terao), localized in the chilo¨¦ island, southern chile in the synthesis of the nap-gis zeolite. this zeolite crystallized with different morphologies from gels prepared from the diatomites. the analyzed gels had the following chemical composition: na2o= 0.87; ¦Ál2o3= 1.0; sio2= 8.7; bcta= 0.87: h2o= 217.5. the synthesis was carried out under hydrothermal conditions, at 110¡ãc and autogenic pressure. the activation was done with naoh in presence of cetiltrimetilamonium bromide (ctab). the zeolite nap-gis crystals, synthesized from the quiquel diatomite gel, are mainly bladed aggregated crystals and those crystallized from the terao diatomite gel exhibit a triangular like morphology. the synthesized solids were identified by x-ray diffraction (xrd) and characterized by scanning electron microscopy- energy dispersive x-ray spectroscopy (sem-eds).
