The possibility of partial or complete replacement of PbO in fusible glass solders by less toxic components is investigated. It is found that it is impossible to find a full-fledged replacement for glasses in the lead-borate eutectic, used as the glass base in glass soldering compositions for sealing glass ceramic packages of integrated microcircuits at temperatures 390 – 420°C, within the systems PbO – P2O5– ZnO – B2O3,V2O5– P2O5– ZnO – B2O3, and TeO2– PbO – V2O5– Bi2O3 with different additives and total mass content of class-I hazard components not exceeding 70%.
