MSDS - Silver Oxide - Revised March 7, 2013
1 - Product Identification
Synonyms: Silver(I)Oxide, Argentic Oxide, Silver Monoxide
Formula Weight: 231.74 (93.10% Silver metal by weight)
Chemical Formula: Ag2O
2 - Composition
3 - Hazards NFPA 704
Health Rating: 2 - Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury.
Flammability Rating: 0 - None
Reactivity Rating: 1 - Normally stable, but releases oxygen at temperatures above 280°C (536°F).
Contact Rating: 3 - Severe (Corrosive). Avoid skin contact, especially if skin is wet or moist.
Lab Protective Equip: Safety goggles and/or face shield. Latex gloves. Good ventilation.
Storage Color Code: Yellow (Reactive)
4 - First Aid Measures
Inhalation: Remove to fresh air. Dust will sting the nasal passages. Get medical attention as soon as possible.
Ingestion: If swallowed, give 2-4 cupfuls of milk or water. Get medical attention as soon as possible.
Skin Contact: Flush skin with plenty of water for at least 15 minutes. Household Hydrogen Peroxide will reduce Silver Oxide to Silver Powder with evolution of Oxygen gas and heat. Get medical attention as soon as possible.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed.
5 - Fire Fighting Measures
Fire: Strong oxidizer. Contact with other material may cause fire.
Explosion: Reacts with ammonia to form an explosive fulminate when wet or dry.
6 - Accidental Release Measures
Wear protective equipment. Clean up in a way that doesn't disperse the powder into the air. If it is released into water, add dilute Hydrogen Peroxide to form less harmful Silver Powder.
Special Note: Disposal of Silver Oxide in waste systems connected to a septic tank is guaranteed to destroy the septic bacteria and require pumping out, flushing and seeding with fresh bacteria.
7 - Handling and Storage
Store in a closed container. Silver Oxide is not light sensitive, it does absorb Carbon Dioxide in > 25% humidity.
8 - Exposure Limits; Airborne
OSHA Permissible Exposure Limit (PEL): n/a
ACGIH Threshold Limit Value (TLV): n/a
9 - Physical and Chemical Properties
Appearance: Jet Black fine powder.
Odor: Odorless. The fine dust stings eyes, throat and nasal passages.
Silver Oxide imparts a distinctly metallic taste to water.
Solubility: 0.0002g/1000ml water @ 20°C (68°F).
Specific Gravity: 7.143
Melting Point: 280°C (536°F) - begins to release Oxygen to form Silver Powder.
Boiling Point: Turns to Silver Metal before reaching the boiling point of Silver.
Vapor Density (Air=1): not available
Vapor Pressure (mm Hg): Very low.
10 - Stability and Reactivity
Stability: Stable at room temperature in sealed containers.
Hazardous Decomposition Products: Oxygen.
Incompatibilities: Ammonia - forms explosive Silver Nitride when wet or dry.
Incompatibilities: Hydrogen Peroxide - can release Oxygen in an explosive way, especially when concentrated.
Incompatibilities: Ignites Sulfur, Red Phosphorous, Sulfides of Antimony and Arsenic.
Incompatibilities: Cotton, paper towels, rags, skin, proteins, etc.
Conditions to Avoid: Do not allow Silver Oxide and Ammonia to combine.
