Holmium Oxide (Ho₂O₃) Nanopowder or Nanoparticles, nanodots or nanocrystals are ferric and ferrous spherical or faceted high surface area oxide magnetic nanostructure particles. Nanoscale Holmium 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 Holmium 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 Holmium Oxide Nanocrystals include as a flame retardant in coatings, plastics, fiber and textiles and in certain alloy and catalyst applications. Further research is being done for their potential electrical, magnetic, optical, and bioscience properties. Holmium Oxide Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Holmium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f¹¹6s². In its elemental form holmium's CAS number is 7440-60-0. The holmium atom has a radius of 174.3.pm and it's Van der Waals radius is unknown. Holmium has the highest magnetic moment (10.6µB) of any naturally occurring element. Because of this it has been used to create the highest known magnetic fields by placing it within high strength magnets as a pole piece or magnetic flux concentrator. This magnetic property also has value in yttrium-iron-garnet (YIG) lasers for microwave equipment. Holmium 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. Holmium lases at a human eye safe 2.08 microns allowing its use in a variety of medical and dental applications in both yttrium-aluminum-garnet (YAG) and yttrium-lanthanum-fluoride (YLF) solid state lasers. The wavelength allows for use in silica fibers designed for shorter wavelengths while still providing the cutting strength of longer wave length equipment.
