Unlike solids, however, liquids expand in all directions since they do not have fixed shapes. Thus, volume expansion is common in liquids, and linear expansion does not occur. Thermal Expansion and Contraction Examples Thermal expansion and contraction occur every day and there are numerous real-...
S.Matsuoka, inHandbook of Thermal Analysis and Calorimetry, 2002 2.1Free volume and excess enthalpy in the condensed state The thermalexpansion coefficientα1of many liquids is about 7×l0−4K−1, and that of theglassy state(as well as the crystalline state),αsfor polymers is about 2×...

The occurrence of cracks and delamination are governed by the penetration depth of CMAS into the TBCs, giving rise to localized tensile stress at the surface as it undergoes cooling. The formation of stresses is mainly attributed to the thermal expansion mismatch during cooling. More specifically,...
where λ0, D and n are the resonance wavelength, effective diameter and refractive index of the cold cavity, respectively. dn/dT and (1/D)(dD/dT) represent the coefficients of the thermal refraction and thermal expansion of the cavity, respectively. The temperature dynamics can be described ...
Examples of phosphates showing negative thermal expansion are the diphosphate–divanadate solid solutions ZrP2−xVxO7 and the microporous aluminophosphate AlPO-17 which shows a particularly large effect (Attfield and Sleight, 1998). Zirconium tungsten phosphate Zr2(WO4)(PO4)2 (ZWP) exhibits the ...
The formation of HfMo2O8 leads to crack formation and delamination because of its negative thermal expansion coefficient, which means the inward diffusion of oxygen is the dominant degradation mechanism for concentrating solar power systems [101]. In addition, TMNs have attracted significant attention ...
