Silver carbonate supplier distributor Manufacture in krishnapatnam Nellore Andhra Pradesh india Asia

VIZAG CHEMICAL supplier Silver carbonate is the chemical compound with the formula Ag2CO3. Silver carbonate is yellow but typical samples are grayish due to the presence of elemental silver. It is poorly soluble in water, like most transition metal carbonates.

Uses

The principal use of silver carbonate is for the production of silver powder for use in microelectronics. It is reduced with formaldehyde, producing silver free of alkali metals:

    Ag2CO3 + CH2O → 2 Ag + 2 CO2 + H2

Silver carbonate is used as a reagent in organic synthesis such as the Koenigs-Knorr reaction. In the Fétizon oxidation, silver carbonate on celite serves as an oxidising agent to form lactones from diols. It is also employed to convert alkyl bromides into alcohols. As a base, it has been used in the Wittig reaction.

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.

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).
