In this study, the effects of porosity on sound properties, elastic moduli (Young's modulus, shear modulus and Poisson's ratio) and tensile strength of sintered compacts were investigated. The sound velocities were obtained by an acoustic pulse method.<BR>At the same porosity, the elastic moduli increased with increasing of sintering temperature. In the case that the longitudinal wave velocity and sintering temperature were known, the porosity of measurement area (partial porosity) was able to calculated.<BR>In addition, the prediction of fractured position with an acoustic microscope and the calculation of partial porosity of fractured position from measurement of the longitudinal wave velocity were carried out, we obtained the relationships between elastic moduli, tensile strength and porosity of fractured position. From the results, since the partial porosity of fractured position were larger than the average porosity, the elastic moduli and the tensile strength against average porosity were underestimated in comparison with that against partial porosity of fractured position.
