Abstract
Chromia microspheres were synthesized by the sol-emulsion-gel method. The solvent extraction technique was followed for the preparation of t he sols. Cr2O3 crystallized as single phase in the temperature range 4 00 to 1300 degrees C. Complete crystallization occurred at 1300 degree s C. Spherical morphology of the powder was confirmed by scanning elec tron microscopy. A size range of 3-30 mu m was observed in the powder calcined at 1300 degrees C.
