Description
Dark brown or black powder. Silver oxide is used for polishing glass and for coloring glass yellow. It has also been used at excavation sites for the treatment of Bronze disease. However, it is not as effective as Benzotriazole and can leave dark spots on the surface. Silver oxide is used medicinally as a germicide.
Synonyms and Related Terms
argentous oxide; argenticoxide; silver peroxide; disilver oxide
Risks
- Fire and explosion risk in contact with organic materials or ammonia.
- ecomposes in sunlight to form metallic silver and oxygen.
- Contact may cause iiritation and staining.
