The compound BaZn2Si2O7 shows a high coefficient of thermal expansion up to a temperature of 280 °C, then a transition to a high temperature phase is observed. This high temperature phase exhibits negative thermal expansion. If Ba2+ is successively replaced by Sr2+, a new phase with a...
The coefficient of thermal expansion (CTE) is a physical quantity that indicates the thermal expansion value of a material upon heating. For advanced thermal management, the accurate and immediate determination of the CTE of packaging materials is gaining importance because the demand for high-power ...

Theory predicts and measurements confirm that anharmonic properties such as the lattice thermal resistivity, the Grüneisen parameter, and the coefficient of thermal expansion generally decrease as a function of increasing density upon compression of solids. The Debye-Grüneisen continuum model further predi...
The thermal expansion coefficient α(T) of CeCusingle crystal has been measured up to 20 kbar in the temperature range from 4.2 K to 260 K in order to study the anisotropic behavior of the α(T) at high pressure. It is found that the contribution of the 4f electron to the α(T) sh...
We use reactive sintering to combine a cobalt-based perovskite with high electrochemical activity and large thermal-expansion coefficient with a negative-thermal-expansion material, thus forming a composite electrode with a thermal-expansion behaviour that is well matched to that of the electrolyte. A ...
