Metal Nano Powder

Boron Nanopowder Nanoscale Boron 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 Boron Oxide Particles are also available in ultra high purity and high purity, transparent, and coated and dispersed forms. 

Boron Nanopowder  have a diverse range of applications in areas such as semiconductors protective coatings, high density fuels and cancer treatment. Boron neutron capture therapy usually relies on soluble, rather than particulate, boron compounds. The use of a novel boron nanoparticle for boron neutron capture therapy. Two hundred and fifty thousand B16-OVA tumour cells, pre-incubated with boron nanoparticles for 12 hours, were injected subcutaneously into C57BL/6J mice. The tumour sites were exposed to different doses of neutron radiation one, four, or eight days after tumour cell inoculation.

Boron Nanopowder (BNPs) are of great interest for applications such as neutron capture therapy of cancer cells, hydrogen generation from water, and high energy density fuels. Water splitting by reaction with boron  used high temperature steam with external heating. Boron carbide is widely used materials for its attractive combination of properties such as high hardness, low density, high melting point, excellent thermoelectric properties, etc. As well, sintered boron carbide is commonly used, also its powder is applicable for many areas of industry.

Boron Nanopowder is a metalloid chemical element with symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar system and in the Earth’s crust. Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals.These are mined industrially as evaporites, such as borax and kernite. Chemically uncombined boron is found in small amounts in meteoroids but is not found naturally on Earth. Industrially, very pure boron is produced with difficulty because of refractory contamination by carbon or other elements. Several allotropes of boron exist: amorphous boron is a brown powder; crystalline boron is silvery to black, extremely hard and a poor electrical conductor at room temperature. The primary use of elemental boron is as boron filaments with applications.

Elemental boron is a highly attractive fuel for propellants and explosives.1,2 Of all the chemical elements, boron has the highest volumetric heat of combustion (140 kJ cm3) and the third highest gravimetric heat of combustion (59 kJ g1), after H2 and Be. These values are over 3 times higher per unit volume, and 1.4 times higher per unit mass, than those of hydrocarbon fuels. 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.
