摘要：
The temperature dependence of the specific electric conductivity of suspensions based on carbonate and carbonate-chloride melts immobilized with alpha-Al2O3 powder was studied. For carbonate-chloride melts immobilized with alpha-Al2O3, the decrease in the specific electric conductivity considerably exceeded the effect associated with a decrease in the volume fraction of charge carriers. The Raman spectroscopy and Xray diffraction analysis showed that there was no chemical interaction of alpha-Al2O3 with the carbonate and carbonate-chloride melt that could lead to the formation of additional nonconducting phases in these systems in the temperature range under study.
