Studies in Lithium Oxide Systems: XII, Li2O‐B2O3‐Al2O3

Abstract
Tentative phase relations in the binary system BnOa‐A12O3 are presented as a prerequisite to the understanding of the system Li2O‐B2O3‐Al2O3. Two binary compounds, 2A12O3.B2O3 and 9A12O3.‐2B2O3, melted incongruently at 1030° f 7°C and about 144°C, respectively. Two ternary compounds were isolated, 2Li2O.A12O3.B2O3 and 2Li2O. 2AI2O3. 3B203. The 2:1:1 compound gave a melting reaction by differential thermal analysis at 870°± 20° C, but the exact nature of the melting behavior was not determined. The 2:2:‐3 compound melted at 790°± 20° C to LizO.‐5Al2O3 and liquid. X‐ray diffraction data for the compounds are presented and compatibility triangles are shown.
