摘要： There is disclosed a novel dry process for the production of hexagonal-system ferrite having the formula: MO.multidot.nFe.sub.2 O.sub.3, wherein n represents a real number of 5.1-5.8 and M represents at least one metallic element selected from the group consisting of Ba, Sr and Pb. The ferrite is baked in the presence of the mixed additive comprising X-agent selected from the group consisting of KCl, NaCl and LiCl; and Y-agent selected from the group consisting of KBO.sub.2, NaBO.sub.2 and LiBO.sub.2 and/or the group consisting of K.sub.2 CO.sub.3, Na.sub.2 CO.sub.3 and Li.sub.2 CO.sub.3. After baking, the mixed additive is completely removed from the resulting ferrite by washing or by a wet-process disintegrating treatment. By changing the mixing ratio of said X-agent to said Y-agent, ferrite crystals having various characteristic properties can be obtained.
