%X Oxidation behavior of lead telluride (PbTe) was systematically investigated at oxygen partial pressures of 0.01 to 100 kpa in the temperature range between 700 and 900 K. Mass loss was observed at moderately low oxygen partial pressures and at high temperatures, while mass gain was observed at high Oxygen paFtial pressures and at low temperatures. Certain Ph-Te-O ternary oxides formed at all conditions. Ph3TeO5 or Ph5TeO7 formed on the sudece of PbTe for the conditions at which mass loss was observed, while PbTeO3 layer or Pb2TeO4/ PbTeO3 multi-layer formed for the conditions at which mass gain was observed.
