Latest Patents

Okumori's latest patents include a process for producing a magnet of strontium ferrite with high performance. This process involves crushing iron ore or mill scale to form a fine powder, which is then heated in the presence of oxygen to create iron oxide with at least 98.0% Fe₂O₃. The iron oxide is mixed with strontium oxide or carbonate, calcined, and subsequently molded in a magnetic field before sintering to yield a high-performance strontium ferrite magnet. Another patent focuses on producing ferrite powder for high-performance ferrite magnets. This process includes milling magnetite or mill scale into a specified particle size, oxidizing the product to achieve a powder containing 98.0% or higher Fe₂O₃, and adding iron oxide from iron chloride or iron sulfide along with strontium or barium compounds. The resulting mixture is calcined, providing a cost-effective method for producing ferrite powder with high magnetic properties suitable for automotive applications.
