Large zeolite ferrierite (FER) single crystal was synthesized according to the method of A. Kuperman et al. in a near non-aqueous solvent. The mechanical properties of zeolite FER single crystal were measured in this paper using MTS Nanoindenter XP with a Berkovich tip. The load–displacement curve of zeolite FER was obtained. According to continuous stiffness measurement (CSM) technique and the calculation method given by W.C. Oliver, the hardness and the elastic modulus of zeolite FER were found to be around 1 GPa and 10 GPa, respectively. Finally, the mechanical properties of large zeolite FER single crystal were compared with SiO 2 standard sample.
