Oxide Nanopowder

Tungsten trioxide nanoparticles are available in the form of nanocrystals or nanodots having a high surface area. They exhibit magnetic properties. Titanium belongs to Block D, Period 4 while oxygen belongs to Block P, Period 2 of the periodic table. Tungsten trioxide nanoparticles are also known as flamenco, rutile, titanium dioxide and dioxotitanium. Titanium Dioxide nanoparticles are known for their ability to inhibit bacterial growth and prevent further formation of cell structures.

Sun creams that contain the transparent nanoscale TiO₂ can be applied much more easily. In addition, their protective effect against harmful UV radiation is much better. At present, high sun protection factors can only be achieved using nanoscale Tungsten trioxide nanoparticles. In recent years, metal oxide nanoparticles have attracted much attention by their potential application in diverse fields including catalysis, magnetic recording media, microelectronics, and medicine.

Tungsten trioxide nanoparticles are a multifaceted compound. TiO₂ is also a potent photocatalyst that can break down almost any organic compound when exposed to sunlight, and a number of companies are seeking to capitalize on titanium oxide’s reactivity by developing a wide range of environmentally beneficial products, including self-cleaning fabrics, auto body finishes, and ceramic tiles.

Tungsten trioxide nanoparticles are mostly used as a white pigment because of its high diffraction index, strong light scattering, incident-light reflection capability and a high UV resistance that make TiO₂ the standard pigment found in white dispersion paints with high hiding power. Since light scattering does not occur anymore in nanoscale particles, the white TiO₂ pigments used are almost exclusively rutile modification particles with grain sizes in the micrometer range. These white pigments are not only found in paints and dyes but also in varnishes, plastics, paper, and textiles.

Tungsten trioxide nanoparticles are a well-known photocatalyst for water and air treatment as well as for catalytic production of gases. The general scheme for the photocatalytic destruction of organics begins with its excitation by supra band-gap photons and continues through redox reactions where OH^-radicals, formed on the photocatalyst surface play a major role.  TiO₂ is non-toxic and therefore is used in cosmetic products (sunscreens, lipsticks, body powder, soap, pearl essence pigments, and tubes of toothpaste) and also in special pharmaceutics. TiO₂ is even used in foodstuffs. TiO₂ photocatalytic characteristics are greatly enhanced due to the advent of nanotechnology.
