| Abstract: | The elastic moduli
for fine particle ZnxCu1-xFe2O4 (x = 0.2, 0.4, 0.6 and 0.8) spinel
ferrite system synthesized by wet-chemical technique have been determined
through infrared spectroscopy and X-ray diffraction pattern analysis. The force
constants for tetrahedral and octahedral sites determined through IR spectral
analysis, lattice constant, X-ray density values through XRD pattern analysis;
have been used to calculate elastic constants like bulk modulus, Young’s
modulus, rigidity modulus, Poisson’s ratio and Debye temperature corrected to
zero porosity. The elastic moduli values for all the compositions are found
larger as compared to conventional ceramically prepared compositions. The
results have been explained on the basis of elastic energy and grain size
reduction effect of fine particle. The observed variation of elastic constants
with zinc substitution have been interpreted in the light of strength of
interatomic bonding. |
