Magnetic analysis as a means of determining the degree of ferritization of barium ferrite powder

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; at _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.Translated from Poroshkovaya Metallurgiya, No. 3 (87), pp. 57–60, March, 1970.
