Electrical Conductivity in Mixed-Alkali Aluminosilicate Melts. -Measurements of the ac conductivity in 25(Na2O + K2O)-yAl2O3-(75-y) SiO2 glass melts with y = 0, 5, 7.5, and 10 mol% at 1000-1400 β’ C show a strong mixed-alkali effect. An increase of the mixed-alkali effect with increasing Al2O3 conte

The valence state of the Cr ion in Ca-doped lanthanum chromite compounds without or with oxygen deficiency has been calculated by means of a tight-binding approximation on the basis of the EHMO approximation. The results indicate that the relative content of Cr 4 ions in La 1Γx Ca x CrO 3 will becom
