About Bismuth Bi powder:
Bismuth, when fresh, is a silvery brittle, crystalline metal. The air often has a pinkish tint. Bismuth element is most diamagnetic and has the lowest thermal conductivity of all metals except mercury. It is characterized by a high electrical resistivity and the highest hall coefficient.

Bismuth – Powder consists of metal nanoparticles with varying colors, ranging from dark grey to black. The colors are determined by the particle size and there is no obvious agglomeration or mixing.
It has the highest electrical resistance of all metals and the strongest Hall effect (that means the most significant increase in electrical resistance in a magnetic fields). Bismuth remains stable in oxygen and water. However, it will dissolve in nitric concentrated air. All bismuth compounds are insoluble when placed into water.

Bismuthimite bismite is the main ore of bismuth. Bismuth can be found naturally in its metal form and as crystals within the sulfides ore of nickel cobalt silver and tin. Bismuth is mostly produced in the USA as a byproduct of copper and lead smelting. Bolivia, Peru’s, Japan Mexico and Canada are the main areas that mine it, but they only produce 3,000 tonnes per year. It is impossible to estimate how much bismuth can be mined. However, it is unlikely that the metal will ever run out.

How is Bismuth Bi powder produced?
It is best to use freshly prepared a-Bi2O3 to produce bismuth powder by reducing it with a mixture of molecular hydrogen and atomic hydrogen at 270degC. It seems that a reduction reaction of a-Bi2 O 3-Bi has taken place without any intermediate phase being formed.
Bismuth powder can be also produced by such processes 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 powder Uses:
Bismuth Powder 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). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications.
Bismuth metal is used in the manufacture of low melting solders and fusible alloys as well as low toxicity bird shot and fishing sinkers. Certain bismuth compounds are also manufactured and used as pharmaceuticals. The industry makes use of bismuth compounds as catalysts in manifacturing acrylonitrile, the starting material for synthetic fibers and rubbers.
Bismuth powder can be used as a lubricant additive: when added 0.1 to 0.3% of Bi nanoparticles to 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 powder can be used in the metallurgical industry: 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 powder 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 Bi powder:
The damp reunion will affect Bi powder dispersion performance and using effects, therefore, Bismuth Bi powder should be sealed in vacuum packing and stored in cool and dry room, the Bismuth Bi powder can not be exposure to air. In addition, the Bi powder should be avoided under stress.

Packing & Shipping of Bismuth Bi powder:
We have many different kinds of packing which depends on the Bismuth Bi powder quantity.
Bismuth Bi powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Bismuth Bi powder shipping:could be shipped out by sea , by air, by express?as soon as possible once payment receipt.
