Bismuth Specification

The Bismuth, with the cas registry number 7440-69-9, is a kind of silver white or tiny red metal. This chemical is soluble in hot sulfuric acid, nutirc acid and aqua regia while insoluble in water. Besides, being stable chemically, it is incompatible with strong acids, strong oxidizing agents, nitrosyl fluoride, fused ammonium nitrate, interhalogen compounds, chlorine. This chemical could be produced from using zone melting method to refine bismuth metal.

Its product categories are including Industrial/Fine Chemicals; Inorganics; FUNGICIDE; Bismuth; Metal and Ceramic Science; Metals; BismuthMetal and Ceramic Science; Catalysis and Inorganic Chemistry; Chemical Synthesis; AAS; AAS CRMsAlphabetic; AASSpectroscopy; Application CRMs; B; BI - BZSpectroscopy; Matrix Selection; Nitrate; Spectroscopy.

The characteristics of this chemical are as follows: (1)#H bond acceptors: 0;  (2)#H bond donors: 0;  (3)#Freely Rotating Bonds: 0;  (4)Polar Surface Area: 0; (5)Exact Mass: 208.980383; (6)MonoIsotopic Mass: 208.980383; (7)Heavy Atom Count: 1; (8)Covalently-Bonded Unit Count: 1; (9)Melting point: 271 °C; (10)Boiling Point: 1560 °C; (11)Density: 9.8 g/mL at 25 °C; (12)Vapor Pressure: <0.1 mm Hg ( 20 °C).

As to its usage, it is widely applied in many ways. It could be used in the preparation of semiconductor high purity material, high purity bismuth chemical and also as the cooling agent in the atomic reactor; It could also be used as the analysis reagent. 

When you are using this chemical, you should be very cautious. For one thing, it is corrosive which may destroy living tissue on contact. For another thing, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water.

Due to so many dangers above, you should take the different measures to deal with different cases. Wear suitable protective clothing, gloves and eye/face protection. And if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice, and if in case of accident or if you feel unwell seek medical advice immediately (show the label where possible). Besides, keep it away from sources of ignition - No smoking.

Additionally, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: [Bi]
(2)InChI: InChI=1S/Bi
