Negative thermal expansion materials † [PDF]
Journal of the Chemical Society, Dalton Transactions, 1999 The ZrW2O8 family of materials has been shown to exhibit the unusual property of negative thermal expansion over a wide temperature range. α-ZrW2O8 itself shows negative thermal expansion from 2 K to 1443 K with a coefficient of thermal expansion α1 of -9.1×10-6 K-1 between 2 and 300 K. This behaviour can be related to the unusual structure of these

Understanding the role of guest ions in the control of thermal expansion of FeFe(CN)6
Results in Physics, 2022 Understanding the role of guest species in framework materials is important to successfully achieve the control of thermal expansion. In this work, the thermal expansion of the Prussian blue analogue FeFe(CN)6 has been effectively tailored from negative,

Journal of Physics: Condensed Matter, 2005 There has been substantial renewed interest in negative thermal expansion following the discovery that cubic ZrW2O8 contracts over a temperature range in excess of 1000 K. Substances of many different kinds show negative thermal expansion, especially at low temperatures.

Zentropy Theory for Positive and Negative Thermal Expansion
Journal of Phase Equilibria and Diffusion, 2022 It has been observed in both natural and man-made materials that volume sometimes decreases with increasing temperature. Though mechanistic understanding has been gained for some individual materials, a general answer to the question "Why does volume sometimes decrease with the increase of temperature?" remains lacking.

EXAFS and negative thermal expansion in CdTe
Journal of Physics: Conference Series, 2009 CdTe is affected by a low-temperature negative thermal expansion (NTE) of the lattice parameter, whose strength and temperature interval are intermediate between those of the iso-structural crystals Ge and CuCl. EXAFS measurements have been performed on CdTe from 19 to 300 K.

On the switching between negative and positive thermal expansion in framework materials
Materials Research Letters, 2019 The control of thermal expansion represents a challenge in materials design. This work shows that the length of the lattice parameter is a key element for controlling thermal expansion. By varying the lattice parameter through external pressure, chemical
