摘要
反钙钛矿结构锰氮化合物是近年发展起来的一类具有各向同性、负热膨胀系数及负热膨胀温度区间可调、金属性能及力学性能优良的新型负热膨胀材料,展现出重要的应用潜力.本文从负热膨胀材料的发展历史、化合物体系、制备方法、负热膨胀性能影响因素及微观机理等方面,阐述了反钙钛矿结构锰氮化合物负热膨胀材料的研究现状及最新发展动态,并对其发展前景进行了分析和展望.
Antiperovskite manganese nitrides are a group of negative thermal expansion（NTE） materials that have been developed rapidly in recent years.They exhibit important potential applications due to isotropic NTE property,controllable coefficient of NTE and NTE operation temperature window,and good metallic and mechanical properties.In this review,state of the arts and recent development in the field of studying antiperovskite manganese nitrides have been summarized and commented,which consist of introduction of history,classification,preparation approaches,influencing factors and mechanisms of NTE for such materials.The prospects are also described for antiperovskite manganese nitrides.
