Various heteroionic forms have been prepared of a purified natrolite, from Co. Antrim, UK, using treatments with concentrated nitrate solutions at 333 K. They have been fully analysed with additional characterisation by thermal and X-ray diffraction ( XRD) methods. The extent of exchange was limited

Diffusion of methane in LTA type zeolites has been calculated from molecular dynamics simulations. Taking into account the polarization interaction of the exchangeable cations in the zeolite NaCaA with the methane molecules, the self-diffusion coefficients in NaCaA decrease by one order of magnitude
