LOW-MELTING GLASS "2LG" Russian patent published in 2015 - IPC C03C3/74

Abstract RU 2540749 C2

FIELD: chemistry.

SUBSTANCE: glass includes components with the following ratio, wt %: PbO 75.9-78.5; PbF₂ 3.9-6.3; B₂O₃ 7.7-7.8; SiO₂ 0.75-1.5; ZnO 4.3-5.1; Cu₂O 0.75-1.5; Bi₂O₃ 1.0-2.0; CdO 1.0-2.0. Coefficient of linear thermal expansion of glass is 105·10^-7K^-1. Temperature of welding is 480-490°C.

EFFECT: increased temperature of welding and sealing for increase of upper limit of working temperature of piezoresonance devices.
