| titleOfInvention | Manufacturing method of magnetite particles |
| abstract | (57) [Abstract] (Modified) [Problem] The present invention is directed to a coercive force of 6.366 to 10.345 kA / m. (= 80-130 Oe) and to provide a method for producing magnetite having octahedral particle morphology. SOLUTION: The present invention introduces an alkaline component in the form of an aqueous solution under an atmosphere of a protective gas and raises the temperature to 50 to 100 ° C. The iron (II) component in the form of an aqueous solution is added while maintaining the After treatment until the Fe (III) content exceeds 65 mol%, the iron (II) component in the form of an aqueous solution is again added to the resulting suspension after oxidation and the resulting suspension is obtained. Treating the suspension with an oxidizing agent at an oxidation rate of 20-50 mol% / hour of Fe (II) until the iron compound contains more than 65 mol% of Fe (III), The suspension consists of filtering and the residue being washed, dried and ground. |
