The elastic behaviour of Cr³⁺ substituted Co-Zn ferrites system; Co_0.7Zn_0.3Cr_<em>xem>Fe_2鈭?em>xem>O₄ where <em>xem>=0.0 to 0.5 in step of 0.1 were prepared by ceramic method. Ultrasonic Pulse transmission method at room temperature was employed to determine the elastic properties of the presently investigated samples. Values of longitudinal and shear wave velocities were increased with an increases in Cr composition <em>xem>. Using these value of velocities; Young's modulus, rigidity modulus, bulk modulus, longitudinal modulus and Poisson's ratio were calculated. The values of moduli were increased with an increases in Cr composition <em>xem>. Debye temperature of all sample were calculate using the Anderson equation and it shows increasing trend with an increases in Cr composition <em>xem>. The behaviour elastic moduli of Co_0.7Zn_0.3Cr_<em>xem>Fe_2鈭?em>xem>O₄ are interpreted in terms of bonding force between atoms.
