Zoyn, in collaboration with China Jiliang University, DMEGC, and Earth-Panda, has made significant research breakthroughs in the precise detection and control technology of strategic key metal elements in magnetic materials, as well as its industrial application. This achievement has been nominated for the First Prize of the Zhejiang Provincial Scientific and Technological Progress Award.

The project addresses critical challenges in the detection of strategic key metal elements in magnetic materials, the influence of element site occupancy on magnetic properties, and precise control of key elements. Supported by national key R&D programs, National Natural Science Foundation key projects, and provincial key R&D initiatives, the research has achieved a series of significant outcomes:

1. Established precise detection technologies to monitor the distribution and lattice site occupancy of strategic key metal elements during production, enabling quantitative analysis of their distribution and state within materials.

2. Studied the migration behavior of key elements during non-equilibrium phase transitions and sintering processes, constructing a mapping model between element states and macroscopic performance.

3. Advanced multi-element, multi-step grain boundary diffusion control technology for heavy rare earth elements and crystal field regulation techniques for permanent magnetic ferrites.

These achievements enable the efficient utilization of strategic key metal elements, establish critical technologies for synergistically enhancing the formulation, processing, and performance of magnetic materials, and facilitate the development of high-performance rare-earth permanent magnets and ferrite products. Expert evaluations have recognized the results as internationally leading in the areas of precise detection of heavy rare earth and precious metals and resource-efficient utilization technologies.

The project has resulted in 32 core invention patents, 25 published papers, and three validated rare-earth element state detection technologies. Additionally, a Curie temperature detection device for magnetic materials was developed, with five national standards led and contributions to 13 other national standards. The research has also led to the development of 35 new products.
