Silver Carbonate – 99.9+% purity
Our Silver Carbonate is new and freshly prepared. The powder has been ground and sifted.
This is a dry, pale yellow-green powder that does not absorb moisture from the air.
It is best to buy it pre-ground and sifted (like ours).
Silver Carbonate Properties:
CAS Number: 534-16-7
Synonyms: Ag2CO3 Silver Carbonate
Formula Weight: 275.75 grams/Mole — (78.23% pure Silver)
Density: 6.08
Melting Point: 210°C ( 410°F ) – Begins to release CO2 to form Silver Oxide – See details below
Boiling Point: 280°C ( 536°F ) – Begins to release Oxygen to form Silver Powder – See details below

Light and/or Heat can degrade Silver Carbonate.
Can be handled safely in very dim room lighting -or- very dim, indirect incandescent lighting.
When exposed to sunlight, it’s surface turns grey within minutes.
Avoid heat above about 100°C (212°F).
It begins to decompose to Silver(I)Oxide as it approaches 160°C (320°F).
Above about 210°C (410°F) it completely decomposes to Ag2O, Silver(I) Oxide.
Silver Carbonate is considered a safe chemical to handle.
Like all chemicals, avoid breathing the dust, excess skin contact, and wear safety glasses.
All sources of Chlorine will change Silver Carbonate into the white Silver Chloride.
Hydrogen Peroxide reduces Silver Carbonate to Silver Powder, though not very efficiently.
Hydrazine reduces Silver Carbonate to Silver Powder very efficiently.
It is not impact sensitive. It won’t explode or ignite when struck between heavy objects.
It is very slightly soluble in water. (.033g / Liter @ 25°C)
It is soluble in dilute Nitric Acid.
Silver Carbonate powder is generally non toxic.
Like all chemicals, avoid breathing the dust, excess skin contact, and wear safety glasses.

Heat Silver Carbonate above 210°C (410°F) for at least 1 hour, or until it all turns completely black.
At this point, it has released all of it’s CO2 and become Silver(I)Oxide (Ag2O)
The “recharged” Ag2O will now absorb Carbon Dioxide from the air, provided humidity is 25% or greater.
When the color turns pale yellow-green, it is now saturated with Carbon Dioxide, forming Silver Carbonate.
To “recharge” the material to hold more Carbon Dioxide, heat it again, repeating these steps.
This cycle can be repeated indefinitely.
