Conductivity and Superconductivity of (Bi,Pb)4Sr3Ca3Cu4Ox Glass-Ceramics

(Bi,Pb)–Sr−Ca–Cu–O glasses, annealed in proper conditions, transform into a granular metal and superconductor. As a result of annealing oxide superconductors belonging to the bismuth family (Bi,Pb)2Sr2CuOx, (Bi,Pb)2Sr2CaCu2Ox, and (Bi,Pb)2Sr2Ca2Cu3Ox crystallize. (Bi,Pb)–Sr– Ca–Cu–O glass-ceramic samples were obtained by annealing the amorphous solid at temperatures between 500◦C and 870◦C. The...

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 ...
