Description

DOES NOT SHIP OUTSIDE THE USA

Our Silver Oxide is new and freshly prepared. The powder has been ground and sifted.
Silver Oxide Properties:
CAS Number: 20667-12-3
Synonyms: Ag2O, Silver(I)Oxide, Argentic Oxide, Silver Monoxide
Formula Weight: 231.74 grams/Mole — (Contains 93.10% Silver)
Density: 7.143
Melting Point: 280°C ( 536°F ) – begins to release Oxygen to form Silver Powder.
Shelf Life: Indefinite when stored in it’s original bottle, securely capped.
This is a dry, brownish black powder that does absorb Carbon Dioxide from humid air.
It is best to buy it pre-ground and sifted (like ours).
Silver Oxide is not light sensitive. (as far as ordinary room lighting is concerned)
It is very slightly soluble in water. (.0002g / Liter @ 20°C)
Although not very soluble in water, it imparts a distinctly metallic taste to water.
It is soluble in dilute Nitric Acid.
It is reduced by Hydrogen gas at 100°C ( 212°F ), forming Silver Powder and water.
NOTE: All Metal Oxides form their respective Carbonates when exposed to Carbon Dioxide (in 25%+ humidity).

Silver Oxide Uses

As a laboratory reagent.
To remove Carbon Dioxide from aqueous solutions in laboratory reactions.
In pollution control filters.
As a precursor to making Silver Powder. ( by heating it above 280°C ( 536°F ) )
As a component in making Silver Oxide batteries.
To remove Chlorine from acid plating baths, and to remove dissolved Chlorine from water.
As an Antibacterial agent for concrete ( 1 Lb Silver Oxide per cubic yard of Concrete (4,050 lbs) ).
As an Antimicrobial agent in some infection resistant surgical fabric materials.
As an Antimicrobial agent in some Swimming Pools, Spas and Fountains.
As a Carbon Dioxide Scrubber :
Nuclear Submarines use Silver Oxide to scrub Carbon Dioxide from their air.
The International Space Station uses Silver Oxide to scrub Carbon Dioxide from their air.
The Space Shuttle uses Silver Oxide to scrub Carbon Dioxide from their air.
=== How Carbon Dioxide Scrubbing Works : ===
• Silver Oxide absorbs CO2 from air when the humidity is > 25%. (Normal air contains 249ppm CO2)
• While absorbing CO2, Silver Oxide turns into the yellow-greenish Silver Carbonate (Ag2CO3).
• Silver Carbonate can then be ‘recharged’ back to Silver Oxide by heating it.
• Silver Carbonate begins to decompose to Silver Oxide as it approaches 160°C (320°F).
• Above about 210°C ( 410°F ) the Silver Carbonate completely decomposes to Ag2O, Silver Oxide.
• In this way, Silver Oxide can be recycled indefinitely as a Carbon Dioxide scrubber.
• • Above about 280°C ( 536°F ) however, Silver Oxide releases Oxygen to form Silver Powder. (not good here)

Storage:
Store Silver Oxide in it’s original dark brown glass bottle, with the lid closed.

It will ignite on contact with Sulfur, Red Phosphorous, Sulfides of Antimony and Arsenic.
It will ignite other readily oxidized substances. Avoid contact with: cotton, paper towels, rags, skin, proteins, etc.
Concentrated, it is explosively decomposed by Hydrogen Peroxide, forming Silver Powder and Oxygen.
It forms extremely explosive crystals of Fulminating Silver when dissolved in Ammonia. (Explosive even when wet)
• Fulminating Silver is the most explosive of all known metal ‘nitrate’ explosives.
Like all chemicals, avoid breathing the dust, excess skin contact, and wear safety glasses.
When pouring Silver Oxide from it’s bottle, it’s fine dust irritates the eyes, nose, throat and lungs.
• Be very careful and plan ahead for this – before handling the Silver Oxide.
If you exhale onto Silver Oxide, it absorbs some of your Carbon Dioxide to form Silver Carbonate.
It is deadly to lower life forms; bacteria, fungi, viruses.
Do not dispose Silver Oxide into Septic Systems or the Municipal Sewage System.
• It kills all of the beneficial microbes these systems rely on.
To properly dispose of Silver Oxide :
• Add 100 volumes of distilled water to 1 volume Silver Oxide powder. (glass container only)
• Add common household Hydrogen Peroxide, very slowly, with lots of stirring. (glass or plastic stirrer only)
• Add Hydrogen Peroxide, stirring, until all of the Black Powder has turned gray. (lots of bubbles – Oxygen)
• You now have reduced Silver Oxide into harmless Silver Powder. (You may want to keep it)
• NOTE : Silver Powder also breaks down the Hydrogen Peroxide, forming Oxygen bubbles.
