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 ...
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 ...
Fisherman's Friend was originally developed by pharmacist James Lofthouse in 1865 to relieve various respiratory problems suffered by fishermen working in the extreme conditions of the northern deep-sea fishing areas.
Bismuth(III) fluoride or bismuth trifluoride is a chemical compound of bismuth and fluorine. The chemical formula is BiF 3. It is a grey-white powder melting at 649 ...
It is a natural bismuth antimonate, in which bismuth has oxidation state 3, and antimony oxidation state 5. Description. Kyawthuite is monoclinic, ...
Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling ...
Bismuth(III) sulfide can be prepared by reacting a bismuth(III) salt with hydrogen sulfide: 2 Bi 3+ + 3 H 2 S → Bi 2 S 3 + 6 H + Bismuth (III) sulfide can also be prepared by the reaction of elemental bismuth and elemental sulfur in an evacuated silica tube at 500 °C for 96 hours. 2 Bi + 3 S → Bi 2 S 3
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 .
