Abstract
The micromechanical compressive response of siliceous ZSM-5 single-crystals (silicalite) has been measured using an in-house-built micromechanical tester.Single-crystals (Ο300 μm) were prepared using the method of Shimizu and Hamada [Angew.Chemie Int.Ed.38 (1999) 2725]. High-quality crystals with no evident microcracks and which were optically transparent were subjected to measurements using single, cyclic and two-directional compression tests.ZSM-5 crystals are highly brittle and prone to microcracking.An average s modulus Ο4 GPa was measured.No difference in Young's modulus between as-synthesized and calcined crystals is detected and little mechanical anisotropy is observed.The cyclic tests reveal gradual stiffness deterioration through a microcracking process.
