CoAl 2 O 4 pigments were synthesized through Liquid-Feed Flame Spray Pyrolysis(LF-FSP) method using metallorganic precursors of cobalt propionate and alumatrane. Theprecursors were dissolved in ethanol and aerosolized into a methane/oxygen flame where itwas combusted to result in nanopowders at a single step. The resulting nanopowders werecollected in electrostatic precipitators and analyzed by x-ray Diffraction (XRD), FourierTransform Infrared Spectroscopy (FT-IR), colorimetry, Field Emission Scanning Electron
