Abstract

Zeolites have important industrial applications including use as catalysts, molecular sieves and ion exchange materials. In this study, three zeolite materials have been characterized by the National Institute of Standards and Technology (NIST) as Reference Materials (RMs): zeolite Y (RM 8850), Linde Type A (RM 8851) and ZSM-5 (RM 8852). They have been characterized by a variety of chemical and physical measurement techniques: X-ray fluorescence, gravimetry, instrumental neutron activation analysis, nuclear magnetic resonance, calorimetry, synchrotron X-ray diffraction, neutron diffraction, laser light extinction, laser light scattering, electric sensing zone, X-ray sedimentation, transmission and scanning electron microscopy and optical microscopy. The chemical homogeneity of the materials has been characterized. Reference values are given for the major and trace element concentration and for the Si/Al and Na/Al ratios. Information values are given for enthalpy of formation, unit cell parameters, particle size distribution and refractive indices. Comparisons are made to literature unit cell parameters. The RMs are expected to provide a basis for intercomparison studies of these zeolite materials.
