Unlike the lighter pnictogens nitrogen, phosphorus, and arsenic, but similar to antimony, bismuth does not form a stable hydride. Bismuth hydride, bismuthine (BiH 3), is an endothermic compound that spontaneously decomposes at room temperature. It is stable only below −60 °C. [5] Bismuthides are intermetallic compounds between bismuth and ...
In atmospheric chemistry, mixing ratio usually refers to the mole ratio r i, which is defined as the amount of a constituent n i divided by the total amount of all other constituents in a mixture: = The mole ratio is also called amount ratio. [2]
Bismuth chloride (or butter of bismuth) is an inorganic compound with the chemical formula BiCl 3. It is a covalent compound and is the common source of the Bi 3+ ion. In the gas phase and in the crystal, the species adopts a pyramidal structure, in accord with VSEPR theory .
Bismuth silicon oxide is a solid inorganic compound of bismuth, silicon and oxygen. Its most common chemical formula is Bi 12 SiO 20 , though other compositions are also known. It occurs naturally as the mineral sillénite and can be produced synthetically, by heating a mixture of bismuth and silicon oxides.

Bismuth subcarbonate (BiO) 2 CO 3, sometimes written Bi 2 O 2 (CO 3) 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 [1] consists of Bi–O layers and CO 3 layers and is related to kettnerite, CaBi(CO ...
Bismuth oxide is occasionally used in dental materials to make them more opaque to X-rays than the surrounding tooth structure. In particular, bismuth (III) oxide has been used in hydraulic silicate cements (HSC), originally in " MTA " (a trade name, standing for the chemically-meaningless " mineral trioxide aggregate ") from 10 to 20% by mass ...
Bismuth titanate ceramics can be produced by heating a mixture of bismuth and titanium oxides. Bi 12 TiO 20 forms at 730–850 °C, and melts when the temperature is raised above 875 °C, decomposing in the melt to Bi 4 Ti 3 O 12 and Bi 2 O 3. [4]
