Silver oxalate

Silver oxalate (Ag
₂C
₂O
₄) is commonly employed in experimental petrology to add carbon dioxide (CO
₂) to experiments as it will break down to silver (Ag) and carbon dioxide under geologic conditions.^[2] It is also a precursor to the production of silver nanoparticles. It is explosive upon heating around 140 degrees Celsius, shock or friction. ^[3]
