By methods of physical‐chemical analysis (DTA, X‐ray diffraction, IR‐spectroscopy) phaseand
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⋅2B2O3‐ Pr2O3⋅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.
