Transformation of heulandite type natural zeolites into synthetic zeolite LTA
Environmental Technology & Innovation, 2021 Abstract This study developed an approach to synthesise zeolite LTA from three different natural heulandite class zeolite deposits (Escott, Avoca, and NextSand). The challenge was to determine the impact of pre-activation of clinoptilolite or heulandite materials upon the synthesis of zeolite LTA. Heulandite (Escott; Avoca) was thermally less stable (
