Phase Evolution and Crystallite Size of Ni_0.25Zn_0.75Fe₂O₄ at Different Calcination Temperatures

Abstract:

The effects of calcination temperature varying from 700 to 1100°C on the phase evolution and crystallite size of Ni_0.25Zn_0.75Fe₂O₄ synthesized using Sol-Gel technique have been investigated. XRD results showed that the Fe₂O₃ phase was formed in Ni_0.25Zn_0.75Fe₂O₄ in the lower calcination temperature. The crystallization increased as the calcination temperature increased and the crystallite sizes of the Ni_0.25Zn_0.75Fe₂O₄ calculated from Scherrer equation were found to be ranged from 16 to 62 nm which increased when calcination temperature increase. Raman results further confirmed the presence of spinel structure in the samples.
