Fluoride Technology for Obtaining Magnetic Materials Based on Nd-Fe-B. Kinetics of Fluorination Processes of Neodymium and Iron Oxides

In the devices, where the interaction of magnetic field sources is used, it is effective to replace the electric power of a magnetic field with a permanent magnet. Rare earth permanent magnets based on neodymium-iron-boron are the most promising, since they have higher magnetic and mechanical characteristics, they are cheaper and more available. The article discusses a fundamentally new fluoride technology for obtaining fluoride materials, the data on the kinetics of fluorination processes of oxides of neodymium, iron and their mixtures are given.
