Latest Patents

Nengjun Yu holds a patent for a "High-resistivity sintered samarium-cobalt magnet and preparation method thereof." This invention discloses a method for creating a high-resistivity sintered samarium-cobalt magnet. The process involves preparing fluoride or oxide into nano-powder using high-energy ball milling. The samarium-cobalt magnetic powder is then prepared separately through rolling ball milling or high-speed jet milling. A specific electric field is applied in a fluoride suspension to ensure that the fluoride nano-powder evenly covers the surface of the samarium-cobalt magnetic powder. This invention successfully overcomes the technical bottleneck where fluoride or oxide improves the resistivity of a samarium-cobalt magnet but deteriorates its magnetic properties. Nengjun Yu has 1 patent to his name.
