Silicon Oxide (SiO2) Nanopowder, Silica Nanoparticles or nanodots are high surface area particles. Nanoscale Silicon Oxide Nanoparticles or Silica Particles are typically 5 - 100 nanometers (nm) with specific surface area (SSA) in the 25 - 50 m 2 /g range. Nano Silicon Oxide Particles are also available in Ultra high purity and high purity 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. Research into applications for Silicon Oxide nanocrystals includes use as a dielectric coating, in solar cell applications, as a high temperature insulator, as a gas sensor and for use in other coatings, plastics, polymers and wire and further research for their potential electrical, optical, imaging, and other properties Silicon Oxide Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.

Silicon is a Block P, Group 14, Period 3 element. The electronic configuration is [Ne] 3s² 3p². In its elemental form silicon's CAS number is 7440-21-3. The silicon atom has a radius of 117.6.pm and it's Van der Waals radius is 210.pm. Silicon is one of man's most useful elements. It makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, being exceeded only by oxygen. The Czochralski process is commonly used to produce single crystals of silicon used for solid-state or semiconductor devices. Silica, as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties.
