GLASS FOR SOLDERING WITH ALUMINIUM ALLOYS Russian patent published in 2022 - IPC C03C8/24 

FIELD: glass.

SUBSTANCE: invention relates to compositions of glasses allowing for production of a sealed soldered joint with aluminium alloys used in the creation of high-tech production of complexes for processing agricultural raw materials as components of process equipment (e.g., a seed supply tray in a colour sorter). Glass for soldering with aluminium alloys, including SiO₂, B₂O₃, MgO, Na₂O, K₂O, MnO₂, Sb₂O₃, additionally comprises Li₂O, ZrO₂, HfO₂ with the following ratio of components, wt%.: SiO₂ 60 to 65; B₂O ₃ 4 to 10; MgO 1 to 9; Li₂O 8 to 13.5; Na₂O 3.5 to 8; K₂O 1 to 8; HfO₂ 2 to 9; ZrO₂ 1 to 8; MnO₂ 1 to 8.5; Sb₂O₃ 0.5 to 1.5.

EFFECT: increase in the wear resistance of a vitreous dielectric for soldering with aluminium alloys.
