CoAl2O4 is one of the most important blue pigment with spinel-type structure. It is an idiochromatic (self-coloured) ceramic pigment prepared in laboratory by Thenard in 1807 by reaction of cobalt arsenate and cobalt phosphate with Al2O3 at high temperature. It has been applied in decorating porcelains, ceramics, plastics, paints, rubbers, glass, cement. It has great thermal stability, low temperature sinterability and high mechanical resistance. Besides, it is used in heterogeneous catalysis in CO2 reforming of CH4, as CO and CO2 gas sensing in mesoporous form and it is employed in NOx selective reduction
