Coefficients of Heat Transfer for Liquid Alloys of the Rb–Bi System

Coefficients of Heat Transfer for Liquid Alloys of the Rb–Bi System

The thermal conductivity and thermal diffusivity of liquid alloys of rubidium–bismuth systems with Bi contents of 27.0, 50.0, and 66.7 at % are studied in the range of temperatures from the liquidus line to 1173 K using laser flash method. Equations are obtained for approximating the studied propert...

Beschreibung
Zusammenfassung:The thermal conductivity and thermal diffusivity of liquid alloys of rubidium–bismuth systems with Bi contents of 27.0, 50.0, and 66.7 at % are studied in the range of temperatures from the liquidus line to 1173 K using laser flash method. Equations are obtained for approximating the studied properties. Analysis of the temperature and concentration dependences of thermal conductivity and thermal diffusivity indicates the presence of ionic complexes in Rb–Bi melts that decompose as the temperature rises.
