Method of making a solid magnetic material from Sm2 Fe17 N3-X type intermetallic nitride powder |
| 摘要 |
A method of making a solid magnetic material from Sm2 Fe17 N3-x type intermetallic nitride powder, where 0</=x</=1, comprises the following steps: a-the powder is mixed intimately with glass powder having a conversion temperature Tg between 260 DEG C. and 310 DEG C. and a softening temperature Tf less than 400 DEG C., the proportion of glass powder being between 10% and 30% of the total volume; b-the mixture is compressed to obtain a solid; c-the solid obtained is subjected in a neutral gas atmosphere to a heat cycle during which a temperature not less than Tf+5 DEG C. and not more than 420 DEG C. is maintained for at least one hour.
