Oxide Nanopowder

Boron oxide nanopowder is of great interest for applications such as neutron capture therapy of cancer cells, hydrogen generation from water, and high energy density fuels. Mostly these nanoparticles are used for high-voltage high-frequency electricity, plasma arc's insulators, high-frequency induction furnace materials, semi-conducting solid-phase admixtures, atom reactor's structure materials and many more.

Boron oxide nanopowder has an amorphous structure and its chemical formula is B2O3. It is also an oxide of boron and it becomes crystalline after great annealing. The reactivity of the boron is mainly dependent on the structure whether it is in an amorphous or crystalline structure. It has potential applications in fuels or additive material in the fuels.

Amorphous boron has high density, high melting point, chemically inert, high hardness and thermal stability. It is also used in coating materials and prepares composite materials. Boron oxide usually reacts with water so for synthesis purpose some methods cannot use such as sol-gel method, hydrothermal method. Boron oxide is only prepared by ball-milling. Boron oxide nanopowder used in glasses and also these glasses are utilized for radiation shielding as well as in dielectric applications.

Pure Boron oxide nanopowder is needed for the production of certain types of glasses including optical and telescope lenses, medical glasses (ampoules), electronic glasses and glass-ceramic composites. The general benefits of using B2O3 in glass formulations are reduction of melting temperature, increased thermal resistance, and mechanical strength, and enhanced aqueous and chemical durability.

It is used in the manufacture of chemically bonded firebricks and castables which require resistance to high temperature, abrasion, and corrosion. Boric oxide is used as a binder for magnesia-based refractory bricks and as a stabilizer for dolomite refractory bricks commonly used in steel smelting furnaces.
