Research on oxygen-sensing properties of La_2Ni_xCu_(1-x)O_4 composite oxides
Other atmospheric pollutants such as oxidants and sulfur oxides may produce adverse cardiovascular effects, but the evidence is limited.
Metal oxides contain a metal cation and the oxide anion (O2-); they typically react with water to form Bases or with acids to form salts.
"Attempting to braze a contaminated or improperly cleaned surface will result in an unsatisfactory joint. Silver brazing alloys will not flow over or bond to oxides. Oily or greasy surfaces repel fluxes, leaving bare spots which oxidize and result in voids and inclusions."
