The high temperature corrosion of nickel by PbO-Na₂SO₄ mixtures has been studied at temperature range 880℃-950℃ in various atmospheres. For the case which the content of sodium sulfate in the salt mixture is 10-20㏖%, the corrosion is most severe and the critical corrosion temperature is lowest(about 870℃). Lead oxided and sodium sulfate are contributed to the corrosion of nickel in different manner. At lower temperature, lead oxide was considered to act as dominant corrosive, but at higher temperature, sodium sulfate was. Lead oxide induces uniform corrosion and sodium sulfate does grain boundary corrosion for nickel. The high temperature corrosion of nickel by PbC Na₂SO₄ mixtures is related to the existence of oxygen closely.
