Lead-free low-melting glass composition and low-melting glass composite material and low-melting glass paste containing lead-free low-melting glass composition, and sealing structure, electrical and electronic part and coated part using same

Abstract

A lead-free low-melting glass composition containing vanadium oxide, tellurium oxide, silver oxide and lithium oxide, said composition satisfying the following two relational expressions (1) and (2) in terms of oxides. [Ag2O]≥[TeO2]≥[V2O5]≥[Li2O]  (1) 2[V2O5]≥[Ag2O]+[Li2O]≥40  (2) (In the formula, [X] represents a content of component X, and the unit thereof is “mol %”; the same applies hereinafter.) Thus, it is possible to provide a lead-free low-melting glass composition which enables sealing and adhesion at around the melting point (232° C.) of tin and which has high adhesiveness and stickiness.
