具有负热膨胀的框架结构的共同特征--压力诱导软化

Pressure-induced softening as a common feature of framework structures that have negative thermal expansion

Hong Fang, Martin T. Dove

摘要:

立方硅质沸石的一系列分子动力学模拟的结果表明,压力诱导软化--材料在压力下逐渐变得更可压缩的现象--可能是显示负热膨胀的骨架材料的共同特征。从热力学角度分析了负热膨胀与压力软化之间的关系。

英文摘要:

Results of a series of molecular dynamics simulations of cubic siliceous zeolites suggest that pressure-induced softening -- the phenomenon in which a material becomes progressively more compressible under pressure -- is likely to be a common feature of framework materials that show negative thermal expansion. The correlation between the negative thermal expansion and the pressure-induced softening is investigated on the basis of thermodynamics.
