Buzz-o-sonic was used to measure the Young's modulus of mesophase based sintered parts. The influence of pressure and heating rate on the Young's modulus of these parts were studied by Christian A. Rottmair, J. Bauer, M. Gruhl, A. Volek, R. F. Singer at the Central Institute for New Materials and Processing Technology at the University of Erlangen-Nuremberg1

The Young's modulus results are shown below in figure 1.
