In this study, synthesis of Mn2O3 powders by solution combustion route was carried out. Urea (CH4N2O) and citric acid (C6H8O7 center dot H2O) was used as a fuel material in solution combustion synthesis, while manganese nitrate (Mn(NO3)(2 center dot)4H(2)O) was used as an oxidant. Surface area of Mn2O3 synthesised by urea was calculated as 19,37 m(2)/g and 25,07 m(2)/g after the calcination at 400 degrees C and 500 degrees C, respectively. Surface area of Mn2O3 synthesised by citric acid was calculated as 63,77 m(2)/g when fuel/oxidizer was 1/1, ignition temperature of 250 degrees C and calcination temperature at 500 degrees C. Spherical particles of Mn2O3 having average particle size of 50-60 nm was synthesised by using urea, while foam like porous structure of Mn2O3 was obtained when citric acid was used as a fuel in solution combustion synthesis. Pore diameters between 27 and 55 nm was determined for this powders.
