High Purity Bismuth Bi powder cas 7440-69-9, 99%

About Bismuth Bi powder:
Bismuth when fresh produced is a silvery, crystallized, brittle metallic that often displays a pinkish tint in the atmosphere. Bismuth is the most diamagnetic metal, with a thermal conductivity that is lower than mercury. It is very resistant to electrical current and has the highest Hall coefficient.

Bismuth dust is an spherical type of metal nanoparticle. It comes in colors ranging from dark gray to black, depending on its size.
It exhibits a very high electrical resistance. Also, it has the highest Hall effect among metals. This is when its electrical resistance increases the most 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 of silver, cobalt, nickel and tin. Bismuth is most commonly produced by lead and copper melting, particularly in the USA. Bolivia, Peru' and Mexico are the main areas that it can be found. But, only 3.000 tonnes of this metal is produced annually. It is impossible to know how much bismuth there is, though it appears unlikely that this metal will run out.

How Bismuth Bi powder is produced ?
For bismuth powder production, it is better to use freshly 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 the formation 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; electrolysis with BiBr3 (molten A1Cl3), reduction of aqueous solutions in bismuth sodium salts by various agents, cathodic reductions of bismuth dioxide.

Bismuth powder Uses:
Bismuth Powder is for the preparation of pressed bonded targets. High-surface area powders can also be used in applications such as water treatment, fuel cell or solar applications.
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 rubber and synthetic fibers.
Bismuth dust can also be used to lubricate the surface. By adding 0.1- 0.3% of bi nanoparticles to grease, it will make a selflubricating, self laminating layer to protect your machine.
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 dust can be used for magnetic materials. The thermal neutron absorb cross-section of bismuth is smaller, the melting point is lower, and boiling point are higher, making it a suitable heat transfer medium to use 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.
