Bismuth boasts a number of outstanding characteristics such as low melting point and specific gravity. It also has volume expansion and contraction during solidification.
Particle Size: 80nm
About Bismuth Bi powder:
Bismuth when fresh produced is a silvery crystalline and brittle metal that often gives off a pinkish hue in the atmosphere. Bismuth is the most diamagnetic metal. It has a lower thermal conductivity than all other metals except mercury. It is very resistant to electrical current and has the highest Hall coefficient.
Bismuth dust is an amorphous spherical material with colors ranging from dark gray to black, depending on their size.
It exhibits a very high electrical resistance. Also, it has the greatest Hall effect of all metals (that is to say that there is the greatest electrical resistance in magnetic fields). Bismuth can be dissolved in concentrated nitric oxygen, and is therefore stable to both water and oxygen. Bismuth salts all form insoluble compounds when they are added to water.

Bismuthimite, bismite, and cobalt are the two most important bismuth ores. Bismuth can occur naturally in the metal and as crystals within the sulfides minerals of cobalt silver, nickel and silver. Bismuth is most commonly produced by lead and copper melting, particularly in the USA. Bolivia, Peru' and Mexico are the main areas that it is found. It can be found only in a total of 3.000 tonnes each year. It is impossible to know how much bismuth there is, though it appears unlikely that this metal will run out.

How is Bismuth Bi-Powder made ?
For bismuth powder production, it is better to use fresh prepared A-Bi2O3. To do this, reduce the solution with a mix of molecular and atomic hydrogen at 220C. A reduction reaction between a-Bi2O3 and a-3-Bi took place, without any intermediate phase.
Bismuth powder may also be produced using such methods as mechanical comminution and electrolysis at high current densities of nitrate or sulfate solution, electrolysis with methyl alcohol and glacial acid of BiCl3, and electrolysis with BiBr3 in A1Cl3.
Bismuth powder Uses:
Bismuth Powder is for the preparation of pressed or bonded targets. It can also be used in Chemical Vapor Deposition(CVD) as well as Physical Vapor Depositions (PVD), including Low-Temperature Organic Evaporation and Atomic Layer Depositions (ALD), Metallic-Organic (MOCVD), Chemical Vapor Depositions (MOCVD). High-surface area powders can also be used in applications such as water treatment, fuel cell and solar application.
Bismuth material is used to make low melting solders, fusible alloys and bird shot as well low-toxicity fishing sinkers. Bismuth compounds may also be used to make pharmaceuticals. Industry uses bismuth compounds to create catalysts when producing acrylonitrile. It is used as the base material for rubbers and synthetic fibers.
Bismuth dust can also be used to lubricate the surface. By adding 0.1- 0.3% of bi nanoparticles to the grease, it will make a selflubricating, self laminating layer to protect and improve the performance.
Bismuth dust may be used in the metalurgical industry. They can be added to cast iron, steel, and aluminum alloys, which will improve its cutting performance.
Bismuth dustcan serve as magnet materials. The thermal neutron absorb cross-section of bismuth is smaller, the melting point is lower, and boiling point are higher, making it a heat transfer medium in a nuclear reactor.
Bismuth Powder Storage Conditions:
A damp reunion could affect Bi powder's dispersion and use performance. Bismuth Bi should be stored in vacuum bags and kept dry. Bismuth Bi must not be exposed to the air. Additionally, it is important to avoid stressing the Bi powder.
Packing & Shipping Bismuth Bi-Powder:
Many types of packaging are available depending on the Bismuth Bi Powder quantity.
Bismuth Bi powder packaging:vacuum packed, 100g to 500g or one kilogram/bag at 25kg/barrel. Or as requested.
Bismuth Bi-powder shipping: can be sent out by sea or air once the payment has been received.
