Abstract

Antiperovskite manganese nitrides are a group of negative thermal expansion (NTE) materials that have been developed rapidly in recent years. They exhibit important potential applica- tions 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.
