Bismuth Subcarbonate BP
Bismuth subcarbonate (BiO)2CO3, sometimes written Bi2O2(CO3) is a chemical compound of bismuth containing both oxide and carbonate anions. Bismuth is in the +3 oxidation state. Bismuth subcarbonate occurs naturally as the mineral bismutite. Its structure consists of Bi-O layers and CO3 layers and is related to kettnerite, CaBi (CO3) OF. It is light-sensitive.
In modern medicine, bismuth subcarbonate has been made into nanotube arrays that exhibit antibacterial properties.
