About our Silver Carbonate

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

Special Handling Procedures:

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.

Silver Carbonate Uses:

Silver Carbonate is used in Raku pottery to yield beautiful colors.
Nuclear Submarines use Silver Carbonate to scrub Carbon Dioxide from their air.
The International Space Station uses Silver Carbonate to scrub Carbon Dioxide from their air.
The Space Shuttle uses Silver Carbonate to scrub Carbon Dioxide from their air.
Removing dissolved Chlorine from water. (Changes from Silver Carbonate to Silver Chloride)
Biocide against bacteria, yeasts and molds in some Cosmetics.
Biocide against bacteria, yeasts and molds in some Paints and Resins.
Preparation of some types of film for photography.
Removing excess Hydrogen Ions from blood.
Precursor chemical for making Silver Oxide for batteries.
Precursor chemical for making Silver Powder ( by heating it above about 280°C ( 536°F ) ).
Precursor chemical for making Silver Powder ( by the addition of Hydrazine ).
Employed in some Carbon Dioxide sensors.
Laser marking on diamonds. Fine Silver Carbonate is applied to diamond surface before laser fires.
Sometimes used as an alternative process for the preparation of codeinone fro codeine.
Removing hydrogen sulfide and mercaptan sulfur from hydrocarbon oils.
Control leachable mercury in mercury vapor and fluorescent lamps.
Active ingredient in some topical antibiotic creams ( about 1% Silver Carbonate ).
Used in some tooth surface treatments to prevent cavities.
Used in the manufacture highly conductive polymers.
Used in the manufacture of a catalyst to produce ethylene oxide from ethane.
Preparing a metal oxide catalyst for the production of acrylic acid.
Used in preparing a stain to make cells more visible when viewing under a microscope.
Antibacterial agent for concrete ( at least 1 Lb Silver Carbonate per 4,050 Lbs Concrete ).
Used as an anti microbial agent in some infection resistant surgical fabric materials.
Used to help prevent bacteria from growing on Latex (mixed into the Latex before it is formed).
Used to help prevent bacteria from growing on Glass (when melted into the glass).
Used as an agent in the manufacture of Cilostazol.

Storage:
Store Silver Carbonate in it's original dark brown glass bottle.
Keep bottle in dim cabinet and away from bright lighting of any kind, especially sunlight.

How Silver Carbonate is used to scrub Carbon Dioxide:

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.
