WebOct 21, 2005 · For comparison, a typical Poisson's ratio for ceramics is 0.25 and the Poisson's ratio of polycrystalline silicon, another MEMS ceramic, is 0.22. Also, the bulk values have been reported as 0.13–0.14 although one needs to carefully consider the processing methods when comparing to bulk ceramic Poisson's ratio values since … Webmodulus varies from 130.2 GPa to 187.5 GPa, Poisson's ratio varies from 0.064 to 0.361, and shear modulus varies from 50.92 GPa to 79.4 GPa.
