Progress in Research on Negative Thermal Expansion of ZrW2O8
负热膨胀”氧化物材料ZrW2O8的研究现状

Zirconium tungstate shows a strong negative thermal expansion from 0.3K up to its decomposition temperature of 1050K. This behavior is especially unusual because the thermal contraction is isotropic over its entire existence range. Recent progress on the unusual negative thermal expansion properties and the origin of ZrW2O8 were reviewed. This paper also discussed the phase transition and its mechanism of zirconium tungstate ZrW2O8
