Abstract
The elastic properties of zinc-substituted lithium ferrites of various comp ositions sintered at 1300 degrees C were measured at room temperature using the ultrasonic pulse transmission technique. The Values of Young's modulus (Y) and the rigidity modulus (n) are found to decrease with increase of zi nc content. The elastic moduli of the specimens are computed and corrected to zero porosity. The variation of Y and n with composition is interpreted in terms of binding energy. (C) 2000 Elsevier Science B.V. All rights reser ved.
