MAGNET AUS SELTENEN ERDMETALLEN FÜR MRI ABTASTER HERGESTELLT AUS AUFBEREITETEM, PR-ND ENTHALTENDEM ERZRESIDUUM |
摘要 |
A permanent magnet for an MRI scanner is made by removing extraneous elements from an ore containing rare earth elements to leave elements Pr and Nd therein, and then selectively stripping therefrom a portion of the element Nd as a byproduct to leave an ore residuum including both elements Pr and Nd therein. The residuum is alloyed with a transition metal to form an alloy therewith. The alloy is then formed into a rare earth permanent magnet configured for use in the MRI scanner. |
