By methods of physical‐chemical analysis (DTA, X‐ray diffraction, IR‐spectroscopy) phase‐ and glass formation in Li2O‐Pr2O3 B2O3 system was researched in zone, which is enriched with boric anhydride. According to the results of three quasi binary sections: Li2O⋅3B2O3− Pr2O3⋅3B2O3; Li2O⋅2B2O3-Pr2O3⋅3B2O3; Li2O⋅2B2O3Pr2O3⋅B2O3, as well as materials about glass formation in binary Li2O−B2O3‐ and Pr2O3−B2O3 systems the zone of glass formation and glass transition diagram of Li2O‐Pr2O3‐B2O3 was defined.
