Abstract
The present disclosure provides a spherical medical tantalum alloy powder, a preparation method therefor and a use thereof, the preparation method comprising the following steps: S1. conducting preliminary plasma spheroidization on a pure tantalum powder to obtain a spherical pure tantalum powder; S2. mixing the spherical pure tantalum powder obtained from S1 with a pure copper particle and a pure silver particle, and then subjecting the mixture to a planetary ball milling to obtain a mixed metal powder; and S3. conducting plasma spheroidization on the mixed metal powder obtained in S2, and then sieving and filtering to obtain the spherical medical tantalum alloy powder. In the present disclosure, through the preparation method combining two-stage plasma spheroidization technology with planetary ball milling technology, the burnout of copper and silver can be reduced, and the spheroidization rate of the tantalum alloy powder can be further improved.
