Abstract

Present work reports the preparation of bright blue CoAl2O4 spinel particles by low
temperature soft chemical route using urea or glycine as fuel in this paper. The
characterization of the resulting powder was done using x-ray diffraction (XRD), particle
size analysis and scanning electron microscopic (SEM) techniques. Pure CoAl2O4 spinel
particles were prepared at relatively low temperature using this soft chemistry route at a
very short duration (< 10 minutes) which is also very simple than other techniques such as
solid state reaction, ceramic methods and so on. From the particle size analysis, it was
found that the spinel particles with low diameter (below 35 μm) were formed. The SEM
photographs showed the formation of fluffy morphology with porous structure.

Keywords: Cobalt aluminate spinel, low temperature soft chemistry route, XRD, SEM.
