Abstract

Within ceramic technology using sodium as a flux component by precipitation from the melt obtained microfine powder of hexagonal barium ferrite. Defined functional magnetic parameters: the coercive force, and a constant effective magnetic anisotropy field and the maximum magnetic energy. The level of the received parameters corresponding to the requirements of the hard magnetic powder materials.
