At the heating temperature of 70°C, 59% of (Mn,Fe)2O3 was obtained with its particle size around 1-10 nm. By applying sol-gel method, the iron sand was processed into iron (III) nitrate using nitric acid. Then Iron (III) nitrate was mixed with manganese (II) nitrate in the EG solvent and heated for 2 hours in 100°C until gel was formed.
