Silver(II) oxide is used to make silver oxide-zinc alkali batteries. It is also used as a reagent in laboratory reactions and forms transition metal-carbene complexes. It is also used as a catalyst to prepare silver metal. It acts as an effective carbon dioxide scrubber and used in nuclear submarines, the international space station and space shuttles. Further, it is used in the manufacture of filters for gas sensors and in some infection-resistant surgical fabric materials and fibrous textile articles. In addition to this, it is used in concrete and in some swimming pools to protect the water from undesired microbes.


Moisture and light sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with hydrazines, amines, sulfur, metal sulfides, strong reducing agents, powdered metals, organic materials and carbon monoxide.
