Abstract
This is a novel way of synthesis with a unique combination of the chemical sol–gel and combustion process. The process is simple, inexpensive and less time consuming as compared to other wet chemical methods which resulting a nano-sized, homogeneous, highly reactive powder. The results revealed that the nitrate–citrate gel exhibits self-propagating combustion behaviour. The structural and electrical properties of the compounds were studied. X-ray diffraction measurements confirm the formation of single phase cubic spinel structure. We note a nonlinear relationship between the structure and composition due to Ni, which demonstrates that structural properties are strongly tied to the Ni substitution.
