Tantalum Oxide ( TaO) Nanopowder or Nanoparticles, nanodots or nanocrystals are ferric and ferrous spherical or faceted high surface area oxide magnetic nanostructure particles. Nanoscale Tantalum Oxide Particles are typically 20-80 nanometers (nm) with specific surface area (SSA) in the 10 - 50 m 2 /g range and also available in with an average particle size of 100 nm range with a specific surface area of approximately 7- 10 m 2 /g. Nano Tantalum Oxide Particles are also available in ultra high purity and high purity, transparent, and coated and dispersed forms. They are also available as a nanofluid 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. Development research is underway in Nano Electronics and Photonics materials, such as MEMS and NEMS, Bio Nano Materials, such as Biomarkers, Bio Diagnostics & Bio Sensors, and Related Nano Materials, for use in Polymers, Textiles, Fuel Cell Layers, Composites and Solar Energy materials. Nanopowders are analyzed for chemical composition by ICP, particle size distribution (PSD) by laser diffraction, and for Specific Surface Area (SSA) by BET multi-point correlation techniques. Novel nanotechnology applications also include Quantum Dots. High surface areas can also be achieved using solutions and using thin film by sputtering targets and evaporation technology using pellets, rod and foil.. Applications for Tungsten Oxide Nanocrystals include in dental imaging because they are sufficiently radiopaque (is impervious to radiation) for good X-ray resolution, and in coatings, plastics, nanowire, nanofiber and textiles and in certain alloy and catalyst applications. Further research is being done for their potential electrical, dielectric, magnetic, optical, imaging, biomedical and bioscience properties. Iron Oxide Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.
Tantalum is a Block D, Group 5, Period 6 element. The number of electrons in each of Tantalum's shells is 2, 8, 18, 32, 11, 2 and its electronic configuration is [Xe] 4f14 5d3 6s2. In its elemental form tantalum's CAS number is 7440-25-7. The tantalum atom has a radius of 143.pm and it's Van der Waals radius is 200.pm. Tantalum is not toxic. Tantalum has a number of interesting properties that make it particularly useful in electronic applications. Tantalum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It has the third highest melting point, surpassed only by rhenium and tungsten, yet it is highly conductive to heat and electricity. This has made it the material of choice for electronic capacitors for most telecommunications and hand held electronics equipment, such as cell phones, laptop computers and pagers. Tantalum compounds, such as the oxide and chloride, are the basis for di-electric coatings. Tantalum is added to glass for its high refractive index. It has various applications in nuclear energy. Due to the close relation of tantalum to niobium in the periodic table, Tantalum's name originates from the Greek word Tantalos meaning Father of Niobe in Greek mythology.
