Bismuth Metal

Bismuth is a silver white to pink metal. It is brittle and easy to be crushed. Its chemical properties are relatively stable. Bismuth exists in nature in the form of free metals and minerals. The selenides and tellurides of bismuth have semiconductor properties.

NC Elements is a professional supplier of high-purity Bismuth metals, in the forms of lumps, chucks, ingots, blocks and beads. The purity levels are 4N, 5N, and 6N. Get a Quote Now! For other semiconductor materials, please check our Semiconductor Materials catalog page.

Typical application:

1. Metallurgical additives

The addition of bismuth can improve the machinability and wear resistance.

2. Bismuth based low melting point fusible alloy

Bismuth is mainly used to make fusible alloy. The melting point range is 47-262 ℃. The most commonly used alloy is bismuth with lead, tin, antimony, indium and other metals, used for fire-fighting devices, automatic sprinklers, and boiler safety plugs.

3. Medical treatment

Bismuth compounds have the functions of astringent, anti-diarrhea, and treatment of gastrointestinal dyspepsia. Bismuth subcarbonate and bismuth nitrite, potassium bismuth subrubberate are used in the manufacture of gastric medicine. Surgery uses the astringent function of bismuth medicine to deal with trauma and hemostasis. In radiotherapy, bismuth based alloy is used instead of aluminum to prevent other parts of the body from being radiated to make protective plates. With the development of bismuth medicine, some kinds of protective plates have been found Bismuth drugs have anticancer effect.

4. Application of bismuth in flame retardant

Among the additives of the flame retardant, the effect of Bi₂O₃ is better than Sb₂O₃, and it is safe and nontoxic. The smoke produced during combustion is very lethal and does not affect the stability of the flame retardant products

5. Application of bismuth in chemical industry

Bismuth yellow pigment, bismuth salt as catalyst.Bismuth hydroxide is used as an additive in plastics, which makes the products glow with beautiful pearl luster. It can also be used to make lead-free pigments and cosmetics.Bismuth chloride is used to reduce fuel tar, creosote and non dry oil.

6. Electronic ceramics

Electronic ceramics containing bismuth, such as bismuth germanate crystal, is a new type of scintillation crystal.

7. Semiconductor

The semiconductor elements composed of high-purity bismuth, tellurium, selenium and antimony are used for thermoelectric couple, low-temperature thermoelectric power generation and thermoelectric refrigeration.
