DSC and DC Conductivity of Bi2O3 · LiF · B2O3 Glasses

Drastic Dependence of the pH Sensitivity of Fe2O3-Bi2O3-B2O3 Hydrophobic Glasses with Composition

Fe2O3-Bi2O3-B2O3 (FeBiB) glasses were developed as novel pH responsive hydrophobic glasses. The influence of the glass composition on the pH sensitivity of FeBiB glasses was investigated. The pH sensitivity drastically decreased with decreasing B2O3 content. A moderate amount of Fe2O3 and a small amount of B2O3 respectively produces bulk electronic conduction and a pH response on glass surfaces...

Influence of manganese ions on spectroscopic and dielectric properties of LiF-SrO-B2O3 glasses

Thermal Conductivity of Polymers, Glasses & Ceramics by Modulated Dsc

This study describes a new method for the measurement of thermal conductivity of insulating materials in the range from 0.1 to 1.5 W/°C m which generally covers polymers, ceramics and glasses. The method is based on Modulated DSC and includes no modification or additions to the apparatus itself. One additional calibration step is required to compensate for heat loss through the inert purge gas ...

Luminescence Properties of TeO2-LiF-Gd2O3 Glasses

In this work, the structural properties and spectroscopic behavior 80 mol.%TeO2-20mol.%LiF glasses which were doped with 0. 05, 0. 2 mole% Gd2O3 have been studied. It was shown that,  by increasing the amount of Gd2O3 the glass stability was decreased. The PL emissions at 431nm and 627nm wavelengths were distinguished by 320nm excitation. The FT-IR analysis showed deformed TeO4 groups in these ...
