A pink ceramic pigment belonging to the Al2O3/Cr2O3 oxide system was s
uccessfully obtained by drying and firing microwave treatments startin
g from inorganic coprecipitated hydroxide gets. Compared with rite pig
ments obtained by conventional industrial ceramic methods, the introdu
ction of microwave treatment can lead to a more continuous and efficie
nt process consuming a small fraction of the energy and time of conven
tional treatment.
