Abstract

The SiO2-ZnO-B2O3-Na2O system glass with various composition was coated on lead telluride (PbTe) surface in order to improve the oxidation resistance of PbTe. The oxidation behavior of the glass-coated PbTe was investigated by measuring the mass change during oxidation, and the effect of PbO · TeO2 addition to the glass was discussed. Microcracks were observed in the SiO2-ZnO-B2O3-Na2O glass coating on PbTe surface. The addition of PbO · TeO2 to the glass reduced the microcracks and improved the adhesion of the glass to PbTe. The mass change of the glass-coated PbTe decreased with increasing PbO·TeO2 content in the glass. The PbTe specimen coated by the srlass contaminer 60 mass%PbO·TeO2 showed no mass changes at 773 K for 360 ks.
