Tungsten Trioxide

Tungsten Trioxide is a chemical compound containing oxygen and the transition metal tungsten. It is obtained as an intermediate in the recovery of tungsten from its minerals.scheelite, is allowed to react with HCl to produce tungstic acid, which decomposes to tungsten trioxide and water at high temperatures.Tungsten trioxide is used for many purposes in everyday life. It is frequently used in industry to manufacture tungstates for x-ray screen phosphors, for fireproofing fabrics and in gas sensors.Due to its rich yellow color, tungsten trioxide is also used as a pigment in ceramics and paints.

Uranium

Uranium is a metallic chemical element in the actinide series of the periodic table. It is used as a colorant in uranium glass, producing orange-red to lemon yellow hues. It was also used for tinting and shading in early photography. The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the planet Uranus. Eugène-Melchior Péligot was the first person to isolate the metal and its radioactive properties were discovered in 1896 by Antoine Becquerel. Research by Enrico Fermi and others starting in 1934 led to its use as a fuel in the nuclear power industry and in Little Boy, the first nuclear weapon used in war.

Vanadyl Sulfate

Vanadyl sulfate is a well known inorganic compound of vanadium. This very hygroscopic blue solid is one of the most common sources of vanadium in the laboratory, reflecting its high stability. It features the vanadyl ion,VO2+, which has been called the "most stable diatomic ion." Vanadyl sulfate is an intermediate in the extraction of vanadium from petroleum residues, a major commercial source of vanadium. It is a component of some food supplements and drugs. Vanadyl compounds mimic the effects of insulin, although humans seem to have no dietary requirement for vanadium.It is used as a dihydrate in dyeing and printing textiles, to make glass, and to add blue and green glazes to pottery.

Vinylsilane

Vinylsilane is an organic chemical. It is a derivative of silane. It is used as a monomer for some copolymer plastics such as ethylene-vinylsilane and ethylene-vinyl acetate-vinylsilane. It is also used as a cross-linking agent during the manufacture of cross-linked polyethylene. The silane group is reactive, and in the presence of moisture, it forms cross-links as the material cures. Moisture-curable polymers are used as electrical insulation in some kinds of cables. Vinylsilane is also used as a coupling agent for treatment of glass fibers in order to form stronger bonds with resin and produce fiberglass with better mechanical properties.
