摘要:

近年來，研究發(fā)現(xiàn)反鈣鈦礦錳氮化合物具有巨大的各向同性負(fù)熱膨脹特性并且其負(fù)熱膨脹系數(shù)和負(fù)熱膨脹溫區(qū)可以調(diào)控，同時反鈣鈦礦錳氮化合物還呈現(xiàn)出磁致伸縮、磁容積效應(yīng)、導(dǎo)熱、導(dǎo)電及近零電阻溫度系數(shù)等豐富的物理性能，因此該類材料受到了人們的高度關(guān)注。反鈣鈦礦錳氮化合物的結(jié)構(gòu)、負(fù)熱膨脹性能、負(fù)熱膨脹機(jī)理及物理力學(xué)性能的深入研究對認(rèn)識該類材料的本質(zhì)及潛在應(yīng)用具有重要的意義。本文簡要介紹了負(fù)熱膨脹材料的發(fā)展歷程，從反鈣鈦礦錳氮化合物的材料體系、負(fù)熱膨脹機(jī)理、物理力學(xué)特性等方面，著重闡述了反鈣鈦礦錳氮化合物負(fù)熱膨脹材料的研究現(xiàn)狀和進(jìn)展，在此基礎(chǔ)上總結(jié)了反鈣鈦礦錳氮化合物負(fù)熱膨脹材料目前存在的問題并對其前景進(jìn)行了分析和展望。

Abstract:

In recent years, it was found that antiperovskite manganese nitrides, with the giant and isotropic negative thermal expansion, show the controllable coefficient and temperature range of negative thermal expansion. Their abundant physical properties, such as magnetostriction, magnetovolume effect, thermal and electrical conduction, and near zero temperature coefficient of resistance, etc, have aroused great interest. The thorough study of crystal structure, negative thermal expansion, mechanism and physical properties of antiperovskite manganese nitrides is significant for essential understanding and potential application. In this review, the development of negative thermal expansion materials especially on manganese nitrides is briefly introduced. The state of the art of studying antiperovskite manganese nitrides are summarized and commented, including classification, negative thermal expansion mechanism, and physical and mechanical properties. The problems and prospects for antiperovskite manganese nitrides with negative thermal expansion materials are described.
