Abstract
ZnFe2O4 nanocrystallites were synthesized successfully by a combination of sol-gel auto combustion and ultrasonic irradiation techniques. The influence of the calcination temperature on the particle sizes was investigated. The particles have been calcined at temperatures varying from 400 to 900 oC. The studies were carried out using XRD and SEM techniques. The gradual increase in the crystallite size with the calcination temperature indicates the formation of bigger particles by the calcination.

Keywords: ZnFe2O4, Sol-gel, Auto-combustion, Ultrasonic, SEM, XRD.
