Effect of Zn Substitution on thestructural Properties of Cobalt Ferrite Nano Particles Prepared Via Sol-Gel Route

Abstract

Zinc substituted cobalt ferrite nanoparticles (CoxZn1-xFe2O4, with x = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5) were prepared via sol-gel route and the effect of zinc concentration on Lattice constant and particle size and powder densitywere investigated. X-ray diffraction analysis confirms the formation of ferrites in nano phase. The Results showed that the particle size decreasing from (22) to (16) nm with increasing the concentration of zinc to the (x= 0.5). The lattice constant increased from (8.36682) to (8.40943)A0 with increasing the concentration of zinc to (x = 0.5), while the theoretical powder density decreased from (5.3225) to (5.2237) g/cm3 by increasing zinc ion concentration to value at (x=0.5).
