| titleOfInvention | High-temperature-stable La(Fe,Si)13-based multi-interstitial-atom hydride magnetic refrigeration material with large magnetic entropy change and preparation method thereof |
| abstract | The invention discloses a high-temperature-stable La(Fe,Si)13-based multi-interstitial-atom hydride magnetic refrigeration material with large magnetic entropy change and a preparation method thereof. By a method for introducing interstitial hydrogen atoms into an interstitial mother alloy which is La1-aRaFe13-bSibXc through hydrogen absorption treatment, a compound which is La1-aRaFe13-bSibXcHd shown as a chemical formula is prepared, wherein the compound has a cubic NaZn13 structure; R is one or more or the combination of rare earth elements; and X is one or more or the combination of C, B and the like. During the hydrogen absorption treatment, required hydrogen content can be achieved through primary hydrogen absorption by controlling hydrogen pressure, temperature and time. The compound can keep stable performance at the temperature of between room temperature and 350 DEG C and under the normal pressure, namely the hydrogen atoms can stably exist in gaps; moreover, the Curie point can be continuously and greatly adjusted in a range from180 K to 360 K through composition change, magnetic entropy change which is over two times higher than the magnetic entropy change of metal Gd can be achieved near room temperature, and loss caused by magnetic hysteresis is avoided. The refrigeration material is a very ideal room-temperature magnetic refrigeration material. |
