Atomistic simulations were used to investigate the surface structure and stability of siliceous and sodium aluminosilicate (Na-A) forms of the zeolite LTA. First, the surface structures were optimized with static lattice minimization. These simulations predict that the single 4-ring termination of {100} and the double 4-ring of {111} are equally stable for siliceous LTA.

Les zeolites de formació natural són rarament pures i es troben contaminades en diferents graus per altres metalls, quars o d'altres zeolites. Per aquest motiu, les zeolites de formació natural es troben excloses de moltes aplicacions comercials importants on la uniformitat i la puresa són essencials.
