Résumé

In this paper La0.8Ce0.2Fe11.47Mn0.23Si1.3H1.8 magnetic refrigerant were prepared by hot pressed method and podwer bonded method respectively, the performance of the samples prepared by two methods were studied. The structure, morphology and magnetic property were researched. The experiment resutls showed that the max magnetic entropy for the boned sample is 11.8J/KgK which is larger than that of hot pressing sample with the max magnetic property of 10.99 J/kgK at the magnetic field of 1.5T. The bending strength and the thermal conductivity of hot pressing sample are both better than the boned sample.
