Microwave synthesis of Al2O3-Cr2O3(ss) ceramic pigments

A pink ceramic pigment belonging to the Al2O3/Cr2O3 oxide system was successfully obtained by drying and firing microwave treatments starting from inorganic coprecipitated hydroxide gets. Compared with rite pigments obtained by conventional industrial ceramic methods, the introduction of microwave treatment can lead to a more continuous and efficient process consuming a small fraction of the energy and time of conventional treatment.
