The SiO2-ZnO-B2O3-Na2O system glass with various composition was coated on 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, and the effects of the glass composition on the oxidation behavior were discussed. The addition of PbO·TeO2 to the SiO2-ZnO-B2O3-Na2O system 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 glass containing 60 mass% PbO·TeO2 exhibited excellent oxidation resistance, which showed no mass changes at 773 K for 360 ks.
