High Purity Tungsten Oxide WO3 powder CAS 1314-35-8, 99.9%

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 1473degC. The boiling point is 1750degC. However, it can subliminate to 850degC. Once melted, it becomes green. The ammonia solution and the concentrated sodium hydroxide solution are stable and insoluble in air.

Technical Parameters of Tungsten Oxide WO3 Pulp:

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 + CaCl2 H2WO4
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 Tungsten Oride WO3 Pulp:
Tungsten Trioxide can be used for many purposes in everyday life. This is often 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;
A tiny amount of tungsten dioxide can be found in some industrial processes as an additive to yellow ceramics.
4. In the shipbuilding sector, tungsten dioxide of tungsten can be used as an important coating or paint anticorrosive.
5. In recent years, tungsten Trioxide has been used in the production of electrochromic or smart windows. 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 material, and the metal that produces tungsten.

Tungsten Oide WO3 Powder Storage:
Tungsten oxide WO3 powder should be stored dry, cool, and sealed of the environment. It cannot be exposed to the air.
