Popis:	X-ray diffraction was performed to construct the phase diagram for the ternary Li2B4O7–Pb3O4–CuO glass system. Three principal regions were identified: (1) a glass-forming region observed at the composition (75 < Li2B4O7 < 100) mol%, (0 < CuO < 35) mol% and (0 < Pb3O4 < 70) mol% in the ternary system, and (100 − x) mol% Li2B4O7–x mol% Pb3O4 where x = 0 up to 70, (100 − y) mol% Li2B4O7–y mol% CuO where y = 0 up to 25 in the binary system;. (2) a crystalline region: all compositions prepared from the binary system Pb3O4–CuO and the ternary system containing Li2B4O7 up to 60 mol%; (3) a partially crystalline region formed between the glass and crystalline regions.
