摘要： A method for safely oxidising roasting NdFeB powder material. The method may include: S1: magnetizing and drying the NdFeB powder material; S2: heating the magnetized and dried NdFeB powder material to spontaneous combustion, and then preparing the spontaneous combustion product into a powder; and S3: magnetizing and then oxidising roasting the powder to obtain NdFeB oxide.
