| 简介 |
An auxiliary alloy powder used for a rare earth material and a preparation method therefor. The preparation method involves subjecting a hydrogen absorption alloy, as an alloy raw material, to smelting to obtain an auxiliary alloy intermediate, subjecting the auxiliary alloy intermediate to hydrogen crushing to obtain auxiliary alloy particles, and subjecting the auxiliary alloy particles to jet milling to obtain an auxiliary alloy powder. The auxiliary alloy powder is formed from an alloy raw material at a specific ratio, has a better hydrogen absorption performance, and can be more rapidly crushed during hydrogen crushing to obtain a more uniform powder with a smaller particle size, such that the technical problem of the introduction of impurities caused by an excessively long preparation process is avoided. |
