Tungsten Nanoparticles: We acquired Tungsten Nanoparticles from Nanoshel and are the obtained nanoparticles are well synthesized as per the requirement. As these nanoparticles has the highest melting point among all the metallic elements. Tungsten nanoparticles have high surface area which can lower the sintering temperatures, low vapor pressure, unusual quantum confinement and grain boundary effects. Due to these properties tungsten nanoparticles are used in Coatings, plastics, nanowires, nanofibres and in Microelectronics films.

Tungsten Nanoparticles: Tungsten is a grayish-white lustrous metal, which is a solid at room temperature. The Nanoparticles comprising tungsten containing multi-metal oxides can be used as pigments. Because they are smaller than the visible wavelengths of light, it leads to visible wavelengths interacting in unusual ways with nanoparticles compared to macro particles. Inorganic pigments ensure homogeneous lattice level mixing of elements in a complex multi-metal formulation. In this context tungsten nanocompounds are ideally suited for creating color and making superior pigments.

Tungsten Nanoparticles: Sodium tungsten oxide nanoparticles, with high purity form are useful in biochemical analysis.Tungsten nanoparticles in metallic form are useful in the analysis of carbon and sulfur by combustion in an induction furnace. The high surface areas of nanoparticles comprising tungsten, with mean particle size less than 100 nanometers make them useful in these applications. Tungsten nanoparticles may also be used to form stronger polymer composites.

Tungsten Nanoparticles: Tungsten nanomaterials offer several unusual benefits as electron emitters as the small size of nanoparticles can enable the formation of very thin film devices, lower the sintering temperatures and sintering times, exhibit inherently low vapor pressure even at high temperatures. They also offer novel compositions for chemical, mechanical polishing applications and electrical contacts. Photocopiers, facsimile machines, laser printers and air cleaners can benefit from charger wires prepared from tungsten comprising nanomaterials. Nanodevice having electrodes, chemical sensors, biomedical sensors, phosphors and anti-static coatings can be prepared from nanoscale powders comprising tungsten.

Tungsten Nanoparticles: Nanomaterials comprising tungsten are particularly useful as direct heated cathode or heater coils for indirectly heated cathodes in cathode ray tubes, displays, x-ray tubes, X-ray device anodes, klystrons, magnetrons for microwave ovens and electron tubes. Multimetal nanomaterials compositions comprising tungsten include those based on rare earths and thoria for high intensity discharge lamps and welding electrodes. The unusual combination of vapor pressure, electrical conductivity and electronic properties make nanomaterials compositions comprising tungsten useful as substrate for high power semiconductor rectifying devices, high voltage breakers, incandescent lamps such as household lamps, automotive lamps, and reflector lamps for floodlight or projector applications, audio-visual projectors, fiber-optical systems, video camera lights, airport runway markers, photo p
