technology of glass, more particularly use as solder and sealant in manufacture of high-temperature thermally sensitive quartz resonators. SUBSTANCE: low-melting glass for soldering and sealing monocrystalline Z-cut quartz comprises wt.%: PbO, 80.5- 82.5; B2O3, 5.5-7.5; SiO2, 0.5-0.9; ZnO, 5.5-6.5; Cu2O, 1.0- 1.5; Bi2O3, 1.0-2.5; Co2O3, 1.5-3.5. EFFECT: lower TKLP and higher softening and soldering temperature of glass. 2 tbl
