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).‎
