摘要
对LaCo13基金属间化合物在磁致冷材料和储氢材料领域中的应用进行了综述,总结了该系化合物的成相规律、替换元素对相稳定性的影响,讨论了近期的研究进展及存在的问题。作为磁致冷材料应用时,LaCo13基金属间化合物在室温具有巨大磁熵变,而作为储氢合金时该系化合物表现出优异的高温电化学容量。虽然在磁致冷和储氢材料领域尚未对LaCo13基金属间化合物进行实用开发,但作为新型绿色能源材料已经展示出良好的应用前景。
The application of LaCo13-based intermetallic compounds as magnetic refrigeration and hydrogen storage materials was reviewed.Phase forming rules and the influence of substituted elements on phase stability for LaCo13-based intermetallic compounds were included.The latest research progress and disadvantages of LaCo13-based intermetallic compounds were discussed.The typical characteristics of LaCo13-based intermetallic compounds have large magnetic entropy change at ambient temperature as magnetic refrigeration material and good high temperature electrochemical capacity as hydrogen storage alloys.LaCo13-based intermetallic compounds are novel green energy materials with good outlook,although they are still not used practically.
