Abstract: Zeolites are widely applied in catalysis, ion exchange, gass eparation and membrane separation of chemistry industry, whose mechanical proper ties have not been researched systematically up to now. The determination of t he mechanical properties of large zeolite ANA single crystal with average size 1 mm in diameter, was reported with MTS Nano Indenter XP to acquire load-displace ment data. With W.C.Oliver method and continuous stiffness measurement (CSM) tec hnique, continuous values of hardness and elastic modulus varying with the inde ntation depth were measured. The hardness and the elastic modulus of zeolite ANA single crystals were found to be around 0.25GPa and 4GPa respectively, the mec hanical properties of two kinds of powder bulk made of zeolite ANA single crysta ls with average size 4mm and 10mm in heights and 13mm in diameter, were also det ermined by traditional Instron 5504 instrument, the elastic modulus of zeolit ANA powder bulk was found to be around 125MPa. The mechanical properties of large zeolite ANA single crystals were compared with-the powder bulk.
