Zirconium (Zr) Nanoparticles, nanodots or Nanopowder are black spherical high surface area metal particles. Nanoscale Zirconium Particles are typically 10-40 nanometers (nm) with specific surface area (SSA) in the 30 - 80 m 2 /g range and also available in with an average particle size of 50 -100 nm range with a specific surface area of approximately 5 - 10 m 2 /g. Nano Zirconium Particles are also available in passivated and in Ultra high purity and high purity and carbon 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 zirconium nanocrystals include nano-crystalline Zirconium alloys for space applications as alternatives for titanium in components of liquid rocket engines (e.g. lines and turbopumps), since they are lighter and less susceptible to embrittlement by hydrogen, and in nanowire, nanofiber and in certain other alloy and catalyst applications . . Further research is being done for their potential electrical, dielectric, magnetic, optical, imaging, catalytic, bio-medical and bioscience properties. Zirconium Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available. Zirconium is a Block D, Group 4, Period 5 element. The electronic configuration is [Kr] 4d2 5s2. In its elemental form zirconium's CAS number is 7440-67-7. The zirconium atom has a radius of 159.pm and it's Van der Waals radius is 200.pm. Zirconium is primarily used in it's oxide or zirconia form. Zirconium dioxide has a high melting point (2,700° C) and a low thermal conductivity. Its polymorphism, however, restricts its widespread use in ceramic industry. During a heating process, zirconia will undergo a phase transformation process. The change in volume associated with this transformation makes the usage of pure zirconia in many applications impossible. |
