| titleOfInvention | Rare earth RE applied to low-temperature magnetic refrigeration2BaZnO5Material and preparation method |
| abstract | The invention relates to rare earth RE applied to low-temperature magnetic refrigeration 2 BaZnO 5 RE is one or two of rare earth Gd, Dy, Ho and Er; under the magnetic field change of 0-2T, the isothermal magnetic entropy is changed to 2.22-11.16J/kg K, and under the magnetic field change of 0-5T, the isothermal magnetic entropy is changed to 10.28-16.91J/kg K; under the change of a magnetic field of 0-7T, the isothermal magnetic entropy is changed to 13.55-19.59J/kg K. Firstly, dissolving raw materials and citric acid in deionized water according to a certain proportion, placing the dissolved liquid into a forced air drying oven to be dried to obtain a powdery sample,and finally, calcining the obtained powdery sample, grinding and annealing to obtain a finished product. The material can be applied to the field of low-temperature zone magnetic refrigeration, the chemical stability of a finished product is good, the preparation method is simple in process, the requirement on preparation time arrangement is not strict, the repeatability is good, and the material can be used for industrial production. |
