Thermal properties of neutron irradiated Se80Te10Ln10 glass

Semiconductor chalcogenide glasses are used in a wide range of applications as solid-state devices, both in scientific and technological fields. In this article, the mechanism of degradation of these materials is studied. The technique was used to measure the variation of thermal conductivity and thermal diffusivity of samples with different exposure times to neutron irradiation. Thermal conductivity and diffusivity increases proportionally with smaller exposure time, while at higher exposure times ...

Assessment of hydrothermal performance by thermophysical characterization of a crimped glass wool building insulation

Insulation is a vital component in the construction industry, notably in this study, glass wool. Maximizing the hydrothermal performance of glass wool is key when dealing with water vapor, humidity and permeability. Although insulation does not generally come in contact with liquids, it is important to consider all outcomes, with likelihood of accidents occurring and the varying levels of workmanship. The transient technique was employed to thermally characterize glass wool ...


Effective thermal conductivity and diffusivity of GeSeSb glasses measured simultaneously as a function of temperature and fit to empirical equations

The effective thermal conductivity and thermal diffusivity was measured for chalcogenide glass samples of the formulation Ge30-xSe70Sbx (x = 10, 15, 20, 25). It was found that both the effective thermal conductivity and thermal diffusivity were independent of temperature up to 160º C. After this point, both properties were found to increase with increasing temperature until they reached a maximum value at a point near the glass transition temperature of the glass. After reaching ...

Thermal transport, thermomechanical, and dielectric properties of chalcogenide Se98–xAg2Inx (x = 0, 2, 4, 6) system

The influence of In content in the Se98-xAg­2Inx (x = 0, 2, 4, 6) system of chalcogenide glasses on the physical properties of the glasses were investigated by the authors. The maximum thermal conductivity and thermal diffusivity value was observed for the sample containing 2 at. % In. The microhardness was found to initially decrease upon doping of In for Se; however, it began to slowly increase after a certain In content had been attained. ...

Thermal Conductivity of Refractory Materials Used in the Glass Production Industry

The thermal conductivities of refractory materials often used in the glass production industry were evaluated experimentally. The transient plane source technique was used for the thermal conductivity testing. Specifically, the single-sided method was used to avoid destroying the refractory materials. The thermal conductivity was measured at various locations and it was discovered that there was a variation in thermal conductivity between the hot and cold faces of the brick....
