A series of Bi1.7Pb0.3Sr2Ca2Cu3O10-AxBy where A Ag and B Ca2CuO3 high-Tc superconductor composite materials have been prepared by the solid-state reaction method. After usual characterization by X-ray diffraction, the bulk density, porosity, electrical resistance, and a.c. susceptibility of the samples were determined and the longitudinal (V1) and shear wave (Vs) velocities were measured by the pulse transmission technique. Using these data, the elasticity parameters such as the Young's modulus (E), rigidity modulus (G), Debye temperature (ØD) and Poisson's ratio (σ) have been evaluated. The variation of elastic moduli with dopant concentration has been explained in terms of binding forces between various atoms of the superconductor.
