Abstract : Abstract The aim of this work is to prepare the room-stable calcium ferrate CaFeO4 from Na2FeO4 chemically synthesized from ferric salts, in an alkali hydroxide medium and hypochlorite which is a particularly effective oxidizing agent in the synthesis, respecting the filtration, purification and drying processes required for the synthesis, because each change can lead to decomposition and decrease in purity. The calcium ferrate synthesis process consists in substituting the sodium ions of the VI ferrate obtained by Calcium by mixing them with a solution of calcium nitrate Ca(NO3)2, in order to study and optimize the essential parameters influencing the yield substitution as well as monitoring of its degradation over time, the reaction yield of which is of the order of 98.7% at a temperature of around [0 ° C - 40 ° C] and of pH = 11 for 30 minutes. The phase obtained was characterized by UV spectrophotometer by measuring the optical density at a wavelength of 507 nm and by the volumetric titration method.
