Conclusions
It has been demonstrated in this work that the magnetic analysis technique is in principle suitable for determining the completeness of ferritization of barium ferrite powders. At a specific saturation-magnetization intensity of 56 G-cm3/g or more, anisotropic magnets with an energy of about 3 · 106 G-Oe are obtained; atσ s=52 G-cm3/g or more, anisotropic magnets are obtained having an energy of more than 2 · 106 G-Oe. The particles of ferritized powders used for such magnets should be approximately single-domain in size.
