The influence of SnO on the physicochemical properties of low-melting glasses in the system Li2O–SnO–P2O5(LSP), intended for use in compositions for vacuum-tight low-temperature bonding of different materials, was studied. The low values of Tg promoted high spreadability of LSP-glass powders at temperatures below 450°C (typical for gluing electronic articles). The mass losses upon boiling of LSP-glasses...
The effect of the granulometric parameters of crystalline lead titanate on the CLTE of soldering glass compositions used for low-temperature vacuum-tight soldering of corundum parts was studied. The optimal values of the specific surfaces of the filler were determined.
