Latest Patents
Yamazaki's latest patents focus on the creation of anisotropic rare earth magnet powder and methods for producing it. The first patent describes a powder that includes RTMB-type crystals of a tetragonal compound made up of rare earth elements, boron, and transition elements. The particles have an average crystal grain diameter ranging from 0.05 to 1 µm. The composition of the powder is carefully balanced, containing 11.5 to 15 atomic % of total rare earth elements, 5.5 to 8 atomic % of boron, and approximately 0.05 to 2 atomic % of copper. Notably, the powder does not include dysprosium, terbium, holmium, or gallium, and exhibits a coercivity of more than 955 kA/m. The second patent further enhances the coercivity of the anisotropic rare earth magnet powder by incorporating enveloping layers of rare earth elements and copper, allowing for improved performance without relying on scarce materials.
