Latest Patents

Masahiko Bannou holds a patent for a novel dry process for the production of hexagonal-system ferrite. The patent describes a method involving the formula: MO·nFe₂O₃, where n represents a real number between 5.1 and 5.8, and M is a metallic element selected from Ba, Sr, and Pb. The process includes baking the ferrite in the presence of a mixed additive comprising X-agent and Y-agent. The X-agent can be KCl, NaCl, or LiCl, while the Y-agent includes KBO₂, NaBO₂, LiBO₂, K₂CO₃, Na₂CO₃, or Li₂CO₃. After baking, the mixed additive is completely removed through washing or a wet-process disintegrating treatment. This innovative method allows for the production of ferrite crystals with various characteristic properties by adjusting the mixing ratio of the agents.
