Scale-up of the Solution Combustion Synthesis of Iron Oxides with the Addition of the Inactive Component FeOx
The solution combustion synthesis of iron oxides from nitrate solutions with a dual fuel comprising urea and citric acid on the earlier synthesized FeO x powder was studied. The possibility of the synthesis of up to 100 g of the desired product under laboratory conditions in a relatively small (4 dm...

Summary: | The solution combustion synthesis of iron oxides from nitrate solutions with a dual fuel comprising urea and citric acid on the earlier synthesized FeO
