Bismuth Granules CAS 7440-69-9 Bismuth Chunks Bi Pellets

About Bismuth Granules:

Bismuth is a freshly produced silvery, crystalline, brittle metal, often presenting a pinkish tinge in the air. The bismuth element is the most diamagnetic, and its thermal conductivity is lower than any metal except mercury. It has a high electrical resistance and the highest Hall coefficient.

Bismuth granules are a kind of metal particles with colors from dark grey to black according to different particle sizes, and there are no mixed colors or obvious agglomeration.

It has a high electrical resistance and the highest Hall effect of any metal (the greatest increase in electrical resistance when placed in a magnetic field). Bismuth granules are stable to oxygen and water but dissolve in concentrated nitric air. All bismuth salts form insoluble compounds when put into water.

The most important ores of bismuth are bismuth and bismite. Bismuth occurs naturally as the metal itself and is found as crystals in the sulfides ores of nickel, cobalt, silver, and tin. Bismuth is mainly produced as a by-product of lead and copper smelting, especially in the USA. The chief areas where it is mined are Bolivia, Peru', Japan, Mexico, and Canada, but only to the extent of 3.000 tonnes per year. There is no reliable estimate of how much bismuth is available to be mined, but it seems unlikely there will ever be a shortage of this metal.

How are Bismuth granules produced?

It is best to use freshly prepared α-Bi2O3 to produce bismuth granules by reducing it with a molecular and atomic hydrogen mixture at 270°C. A reduction reaction of α-Bi2 O 3→Bi has occurred without any intermediate phase forming.

Such processes can also produce bismuth granules as the mechanical comminution of bulk bismuth, electrolysis of nitrate and sulfate solutions at high current densities, electrolysis of BiCl3 in methyl alcohol and glacial acetic acid, electrolysis of BiBr3 in molten A1Cl3, reduction of aqueous solutions of bismuth salts with various agents, and cathodic reduction of bismuth oxide.

Bismuth granules Uses:

Bismuth granules for use in the preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes, including Thermal and Electron Beam (E-Beam) Evaporation, Low-Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Granules are also useful in any application where high surface areas are desired, such as water treatment, fuel cell, and solar applications.

Bismuth Metal manufactures low-melting solders, fusible alloys, low-toxicity bird shots, and fishing sinkers. Certain bismuth compounds are also manufactured and used as pharmaceuticals. The industry uses bismuth compounds as catalysts in manufacturing acrylonitrile, the starting material for synthetic fibers and rubbers.

Bismuth granules can be used as a lubricant additive: when 0.1 to 0.3% of Bi nanoparticles grease in the friction process, the friction surface will form a self-lubricating, self-laminating mask to protect the machine, which will significantly improve the grease performance.

Bismuth granules can be used in the metallurgical industry: they can be used as additives during the production of cast iron, steel, and aluminum alloy, which can improve the cutting performance of the alloy.

Bismuth granules can be used as magnetic materials: bismuth has a smaller thermal neutron absorption cross-section, lower melting point, and higher boiling point, which enable it to be the heat transfer medium used in a nuclear reactor. 

Storage Condition of Bismuth granules:
The damp reunion will affect Bi granules dispersion performance and using effects, therefore, Bismuth Bi granules should be sealed in vacuum packing and stored in cool and dry room, the Bismuth Bi granules can not be exposure to air. In addition, the Bi granules should be avoided under stress.

Packing & Shipping of Bismuth granules:
We have many different kinds of packing which depends on the Bismuth granules quantity.
Bismuth granules packing:vacuum packing, 1kg/bag, 25kg/barrel, or as your request.
Bismuth granules shipping:could be shipped out by sea , by air, by express as soon as possible once payment receipt.
