About Tungsten Oxide WO3 Powder:
Tungsten oxide Oder tungsten trioxide Is an organic substance that has the chemical formula WO3 It is a yellowish powder. This is achieved by adding acid to the soda ash after the fusion.
Tungsten trioxide is It is a light yellow orthorhombic crystal powder. As the powder is heated, it changes color from lighter to darker. It has a specific gravity of 7.16 grams per cm3, a melting point of 1473degC, whereas the boiling point at 1750degC is 17.50degC. The temperature at which it melts is 850degC. It becomes subliminal and green. It is stable in air and insoluble with water and other inorganic acids, except hydrofluoric, and can slowly dissolve in ammonia solution and concentrated sodium hydroxide solution.

Tungsten(VI) oxide The chemical compound known as tungsten-trioxide (WO3), or tungstic anhydride (WO3), contains both oxygen and the tungsten transition metal. It's used to recover tungsten from its mineral sources. Alkalis is used to make WO from tungsten ore. If tungsten is further reduced by carbon, hydrogen gas or other reactions, it becomes pure metal.

Tungsten(VII) oxide can be found in nature as hydrates. This includes minerals such as meymacite (WO3*2H2O), tungstite, WO3*H2O or hydrotungstite. These secondary tungsten mineral minerals can only be found as rare or very scarce.

The crystal structure of tungsten trioxide is temperature-dependent. The crystal structure of tungsten trioxide is temperature-dependent. At higher temperatures than 740oC, it becomes tetragonal. Monoclinic with the space group of P21/n is the most common structure in WO3.

Tungsten trioxide is A strong oxidizing agent. It reacts with rare earth elements like iron, copper, aluminum and manganese. The reaction with gold or platinum makes it into dioxide.

Tungsten Oxide Powder WO3 Performance:
Tungsten Trioxide is an orthorhombic, light-yellow crystal powder. Its color can change to darken when heated. Specific gravity is 7.16g/cubic cmimeter. It melts at 1473C. The boiling point is 1750C. However, it can subliminate to 850C. Once melted, it becomes green. The ammonia solution and the concentrated hot sodium hydroxide solutions are stable and insoluble in air.

How is Tungsten Oxide WO3 Powder produced?
Tungsten trioxide is prepared in many different ways. The CaWO4 (or Scheelite) can react with HCl in order to make tungstic acid. It then decomposes at high temperatures to WO3 or water.
CaWO4 + CaCl2 + CaWO4
H2WO4 - H2O + WO3

An alternative method of synthesizing WO3 in common is to calcinate ammonium paratungstate under oxidizing conditions.
(NH4)10[H2W12O42] * 4H2O - 12 WO3 + 10 NH3 + 10 H2O

Applications of Tungsten Oride WO3 Pulp:
Tungsten Trioxide can be used for many purposes in everyday life. This is most commonly used by industry for the manufacture of Xray phosphors and fireproof fabric, as well as gas sensors. Its rich yellow color makes it a great pigment to use in paints and ceramics.
1.Tungsten oxide is mostly used in calcining the reduction of tungsten to create tungsten flour and tungsten carbide powder. It then gets used for the fabrication of cemented carbonide products like the making of molds and tools.
2.Tungsten trioxide can also be used to manufacture pure tungsten products, tungsten bars, tungsten wires, tungsten electrodes;
3.A small amount can be added to yellow ceramics in industry production.
4. In the shipbuilding sector, tungsten dioxide of tungsten can be used as an important coating or paint anticorrosive.
5. In recent years, electrochromic or smart windows were made from tungsten Trioxide. The light transmission properties of these windows can be altered by applying voltage. They are electrically-switchable. By doing this, users can tint their windows and change the light or heat passing through.
6.X-ray Screen and Fireproof Textile, and the Colorant and Analysis Reagent of Chinaware.
7.Tungsten dioxide can also be used to reduce radiation.
A lot of research has been done on 8.WO3 because it is so important for its electrooptical, ferroelectric, and catalytic functions.
9.Radiation shielding and producing metal tungsten materials
