Author(s): Ajay Lad

Ag₂O : B₂O₃ : SiO₂ Glass System for n=B+Si/Ag and y=B/B+Si 0.7 ≤ y ≥ 0.94 is synthesized, structurally and electrically characterized with a view to have high glass transition temperature (Tg) for solid state electrochemical SO2 gas sensor operating at 400⁰-500⁰C. The glass 25Ag₂O : 60B₂O₃: 15SiO₂ gave maximum conductivity value of the order of 10-3 S/cm at 450⁰C (less than Tg) and low activation energy (Ea = 0.33) due to mixed former effect.
