摘要： The invention discloses a La(Fe,Si)13-based hydride magnetic refrigeration material comprising multiple interstitial atoms and showing a high-temperature stability and a large magnetic entropy change and the method for preparing the same. By reintroducing interstitial hydrogen atoms into an interstitial master alloy La1-aRaFe13-bSibXc through a hydrogen absorption process, a compound with a chemical formula of La1-aRaFe13-bSibXcHd and a cubic NaZn13-type structure is prepared, wherein R is one or a combination of more than one rare-earth element, X is one or more C, B and the like or their combinations. A desired amount of hydrogen is obtained through a single hydrogen absorption process by means of controlling the hydrogen pressure, temperature and period in the process of hydrogen absorption. The compound can be stable under normal pressure, at a temperature of room temperature to 350° C., that is, the hydrogen atoms can still exist stably in the interstices. The Curie temperature of the compound can be adjusted continuously with a wide range of 180K to 360K by changing its composition. The magnetic entropy change that is more than 2 folds of that of Gd can be obtained around room temperature, and the magnetic hysteresis loss vanishes. In view of the above, this material is a desired magnetic refrigeration material applied at room temperature.

摘要： The invention provides a La(Fe,Si)13-based magnetic refrigeration material prepared from industrial-pure mischmetal as the raw material, wherein the industrial-pure mischmetal is impurity-containing and naturally proportionated La—Ce—Pr—Nd mischmetal or LaCe alloy which, as the intermediate product during rare earth extraction, is extracted from light rare earth ore. The invention further provides the preparation method and use of the material, wherein the preparation method comprises the steps of smelting and annealing industrial-pure mischmetal as the raw material to prepare the La(Fe,Si)13-based magnetic refrigeration material. The presence of impurities in the industrial-pure mischmetal has no impact on the formation of the 1:13 phase, the presence of the first-order phase-transition property and metamagnetic behavior, and thus maintains the giant magnetocaloric effect of the magnetic refrigeration material. The preparation of La(Fe,Si)13-based magnetic refrigeration material from industrial-pure mischmetal reduces the dependency on high-purity elementary rare earth raw material; lowers the cost for manufacturing the material; and thus plays an important role in development of the magnetic refrigeration application of materials.
