About Thallium Nanoparticles

Thallium (Tl) Nanoparticles, nanodots or nanopowder are spherical or faceted high surface area metal particles. Nanoscale Thallium Particles are typically 10 - 80 nanometers (nm) with specific surface area (SSA) in the 15 - 20 m²/g range and also available with an average particle size of 300 - 700 nm range with a specific surface area of approximately 1 - 5 m²/g. Nano Thallium Particles are also available in Ultra high purity and high purity and coated and dispersed forms. They are also available as a dispersion through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Other nanostructures include nanorods, nanowhiskers, nanohorns, nanopyramids and other nanocomposites. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers.

Thallium

81 Tl 204.383300000 Thallium

See more Thallium products. Thallium (atomic symbol: Tl, atomic number: 81) is a Block P, Group 13, Period 6 element with an atomic weight of 204.38. Thallium Bohr Model The number of electrons in each of thallium's shells is 2, 8, 18, 32, 18, 3 and its electron configuration is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p¹. The thallium atom has a radius of 170 pm and a Van der Waals radius of 196 pm. Thallium was discovered by Sir William Crookes in 1861 and first isolated by Claude-Auguste Lamy in 1862. Thallium is a post-transition metal that is not found free in nature. Thallium is primarily used for its electrical conductivity as thallium sulfide, which changes with exposure to infrared light. This ability makes the compound useful in photocells. Elemental Thallium Thallium bromide-iodide crystals have been used as infrared optical materials. Thallium has also been used with sulfur, selenium or arsenic to produce low melting glasses which become fluid between 125 and 150 °C, while thallium oxide has been used to produce glasses with a high index of refraction, and is also used in the manufacture of photo cells. Its name is derived from the Greek word thallos, which means twig or green shoot.
