Study of Sol-Gel Auto-Combustion Method Prepare Ni0.6-xZn0.4MgxFe2O4

Abstract

Ni0.6-xZn0.4MgxFe2O4were synthesized by sol-gel auto-combustion method with Zn(NO3.) 2 •6H2O. , Ni(NO3.) )2•6H2O. , Mg(NO3.) )2•6H2O. , Fe(NO3.) )3•9H2O. , COOO2. and NH3•H2O. X-ray diffraction (XRD) analysises show that the sample is single phase and the doping of magnesium makes no difference to nickel-zinc ferrite’s crystal structure; nickel-zinc ferrite has formed after auto-combustion. Scanning electron microscope analysises show that after sintered the sample’s size is more even and the doping of magnesium makes the size smaller and more even too.
