Nano composite of hopcalite/hausmannite was prepared by ceramic method. X-ray diffraction (XRD) technique was used to identify on crystalline phases. The solid state reaction between CuO and Mn2O3 at 1000oC for 4 hours resulted in formation of cubic spinel CuMn2O4 solid with subsequent phase transformation of Mn2O3 to Mn3O4. The morphological and textural characteristics of the as synthesized solid calcined at 1000oC were determined. These results confirm the soft technology of heat treatment in obtaining new composites.
