METHOD OF OBTAINING SOLID MAGNESIUM MATERIAL SmFeN Russian patent published in 2014 - IPC H01F1/59 C01B21/00 C01F17/00 C01G49/00 

Abstract RU 2531393 C1

FIELD: chemistry.

SUBSTANCE: method of obtaining the solid magnesium material Sm2Fe17Nx includes mixing Sm and Fe powders, their mechanical activation and the following nitration. First, mechanical activation in a high-energy-voltage grinder is carried out in the inert atmosphere without content of moisture for 2-3 hours. For nitration in the grinder reactor introduced is ammonia and hydrogen in a ratio of NH3 - 85-95%, H2 - 5-15% and mechanical activation is continued for 5-7 hours. After that, a highly-molecular compound polymethylmetacrylate (PMMA) is introduced in a quantity of 2-4% of the weight of the initial powder mixture and the process of mechanical activation is continued for than 10-15 minutes.

EFFECT: invention makes it possible to reduce the time of obtaining the solid magnesium material and increase its coercive force.
