Overview of bismuth and Nano bismuth powder

Bismuth overview

Bismuth (atomic symbol: Bi, atomic number: 83) is a Block P with an atomic radius of 208.98040, a 15th group, 6th-period element. The number of electrons in each bismuth shell is 2, 8, 18, 32, 18, and 5, and the electron arrangement is [Xe] 4f14 5d10 6s2 6p3. The radius of the bismuth atom in the bismuth Bohr model is 156 pm, and the van der Waals radius is 207 pm. In its elemental form, bismuth is a silvery-white brittle metal. Bismuth is the most diamagnetic of all metals. Except for mercury, its thermal conductivity is lower than any other metal. Element Bismuth has a very high electrical resistance and has the highest Hall effect of all metals (that is, the resistance increases the most when placed in a magnetic field). Bismuth exists in bismuth ore and bismuth ore. It is also a by-product of the extraction of lead, copper, tin, molybdenum, and tungsten. Bismuth was first discovered by early humans. The name bismuth comes from the German word "wissmuth", which means white substance.

Nano bismuth powder

Nano bismuth powder is a dark gray or black powder composed of nearly spherical bismuth particles with a diameter of fewer than 100 nanometers. It can be used in various fields, including manufacturing, metallurgy, and countless professional applications.

Nano bismuth powders are non-toxic, high surface area magnetic nanostructured particles. The applications of bismuth nanoparticles are diverse, including use as industrial lubricant additives, alloying agents in metallurgy, heat transfer media in nuclear reactors, and contrast agents in medical imaging and cancer radiotherapy. Nano-sized bismuth particles are usually 30-80 nanometers (nm), and the specific surface area (SSA) is 15-30 m2/g. There are also ultra-high purity and high purity, coating, and dispersion forms. They are also available as dispersions through the AE Nanofluid production group. Nanofluids are generally defined as nanoparticles suspended in solution using surfactants or surface charge technology. It also provides technical guidance on nanofluid dispersion and coating selection. The chemical composition of the nanopowder is analyzed by ICP, the particle size distribution (PSD) is analyzed by laser diffraction, and the specific surface area (SSA) is analyzed by the BET multipoint correlation technique. High surface area can also be achieved by sputtering targets using particles, rods, and foils and evaporation techniques using solutions and thin films. In addition to customized ingredients and new proprietary technologies for commercial and research applications, we can also produce materials according to customer requirements. Provide typical and customized packaging, as well as other research, technical, and safety (MSDS) data.

Nano bismuth powder application

Lubricant additives.

Nano bismuth powder is still a popular industrial lubricating additive; it can work effectively without causing toxicity or other harm to a given compound.

Nuclear heat transfer.

The unique combination of magnetic, thermal, and other properties of Nano bismuth powder makes this powder the best heat transfer medium for nuclear reactors-only the most suitable materials can be relied on. As a testament to the potential of this field, it is difficult to find more impressive applications.

Medical imaging agent.

Nano bismuth powder can be used as an effective contrast agent for medical imaging and certain forms of cancer treatment, making it one of the most studied nanoparticles. Further medical applications are currently being studied and offer considerable hope.

Metallurgical Industry.

Nano bismuth powder is often used in metallurgy. It is used as an effective alloying agent for the production and connection of certain metals.

Bismuth toxicity

In the clinic, depending on the administration time of bismuth, its toxicity can be roughly divided into acute and chronic exposures. Both exposure doses can cause neurotoxicity, gastrointestinal toxicity, nephrotoxicity, hepatotoxicity, and increased bismuth concentration in blood. Of the heavy metals including lead, mercury, arsenic, and bismuth, it is the latter whose salts are relatively the least toxic. This is probably because of the great insolubility of many bismuth salts that prevents their absorption.
