| 摘 要： | 钨酸锆因其具有各向同性的负热膨胀性能,自1996年发现以来即获得极大关注.目前一些新发现的具有比钨酸锆更大负热膨胀性的材料,如:碳氮键化合物、铁电陶瓷、反钙钛矿结构的锰氮化合物和纳米粒子也同样备受注目.这些化合物的负热膨胀机理或因其具有振动结构,或因其具有磁性或电学性能的转变.这些具有更大负热膨胀特性的材料在制备不受环境温度变化影响的复合材料方面具有潜在的应用价值.

| Abstract: | The isotropic negative thermal expansion compound,ZrW2O8,has been intensively studied since 1996.A variety of newly discovered materials which show even larger negative thermal expansion than that of ZrW2O8 are presently under consideration,namely CN-bridged compounds,ferroelectric ceramics,anti-perovskite manganese nitrides and nanoparticles.The mechanisms associated with the negative thermal expansion effect of these compounds are discussed in terms of their vibrational structures or in terms of their mag... |
