Tungsten Trioxide Powder is a thermally Stable and Water Insoluble Tungsten Compound. Yellow Tungsten Trioxide is Produced from Ammonium Paratungstate. Yellow and Blue Both Oxide Forms are mainly Use for the Production of Tungsten Metal Powder by Powder Metallurgical Methods. Yellow Tungsten Trioxide is a Yellow Finely divided Solid Crystals. It is produced by calcination of ammonium paratungstate (APT) under oxidizing conditions in a Closely Controlled Temperature Environments to remove Water Molecules Form it. 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, WO3 is also used as a pigment in ceramics and paints. Tungsten trioxide has been employed in the production of electrochromic windows, or smart windows. These windows are electrically switchable glass that changes light transmission properties with an applied voltage.This allows the user to tint their windows, changing the amount of heat or light passing through.

Sodium Tungstate Powder has applications as a catalyst, analytical reagent, fireproofing agent. It features a high degree of chemical purity and outstanding water solubility with no residue. It can be used in the manufacture of metal tungsten, tungsten acid, tungsten salts, and dyes, galvanic coatings, and the manufacture of X-ray contrast agents.

Sodium Tungstate Powder is Colorless or white crystalline powder and widely used as catalyst in paint industries, dyes industries, pigments and pharmaceuticals and many more chemical reactions like epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones, it also used in Manufacture of heteropolyacid color lakes used in printing inks, plants, waxes, glasses, and textiles, Analytical reagent, Reagent for alkaloids, uric acid and plasma proteins, Fuel-cell electrode material, and Fire proofing agent, Manufacture of metal tungsten, tungstic acid and tungsten salts.

Sodium Tungstate Powder is an effective Antidiabetic agent when administered orally. It improves pancreatic function and beta cell proliferation. It activates glycogen synthesis through an insulin receptor-independent pathway.

There are dual effects of sodium tungstate on adipocyte biology: inhibition of Adipogenesis and stimulation of cellular oxygen consumption. Sodium tungstate inhibits adipocyte differentiation and regulates the mitochondrial oxygen consumption of adipose cells. These effects contribute to the anti-obesity activity of sodium tungstate and confirm its potential as a powerful alternative for the treatment of obesity.

Sodium Tungstate Powder is used for slurry sampling electrothermal atomic absorption spectrometric determination of indium in soils.

Fused Tungsten Carbide Powder is specially treated, controlled and screened. Each powder is formulated to achieve an optimum value in hardness, abrasion, and erosion as well as impact resistance. In addition and due to excellent wetting properties, fused tungsten carbide powders allow achieving superior infiltration absorption values. These powders are used for manufacturing diamond tools such as saw blades, core bits, drill bits and other infiltrated components. Among the main industrial applications, fused tungsten carbide powders are used for cutting abrasives materials such as asphalt and concrete. Another famous application being the geological surveys and, particularly, the drilling oil & wells.
