NdFeB permanent magnet material has developed rapidly since its invention due to its excellent magnetic properties. It has been widely used in precision electronics, power motors, home appliances and medical fields. It is currently the most commonly used rare earth permanent magnet material.

Since the industrialization of sintered NdFeB magnets, scientific and technological workers have been working hard to improve the temperature sensitivity of permanent magnets. For example, adding a certain amount of Tb and Dy heavy rare earth elements to sintered NdFeB magnets can significantly improve the coercivity of the magnets. force.

As the raw material for grain boundary diffusion processes such as dysprosium and terbium infiltration, the main method for producing rare earth fluoride in the industry is currently the gas-solid reaction method. The raw materials used in this technology are hydrogen fluoride gas and rare earth oxide. However, during the fluorination process, it is easy to cause sintering due to environmental factors such as water vapor and temperature, and the produced rare earth fluoride is severely agglomerated. By improving the fluorination raw materials and conditions, high-quality rare earth fluoride with consistent particle size for NdFeB coating can be prepared.
