Description of 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, and a boiling point of 1750degC. 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 peroxide (WO3), or tungstic anhydride (WOW3), 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. After further reactions with carbon and hydrogen, tungsten dioxide can be reduced to pure gold.

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

The crystal structure of tungsten trioxide is temperature-dependent. The crystal structure of tungsten trioxide is temperature-dependent. At higher temperatures than 740°C, 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 strongly with rare-earth metals, such as iron, copper, manganese, and zinc. The reaction with gold or platinum makes it into dioxide.

How is Tungsten Oxide WO3 Powder produced?

Chemical method

The chemical process is one of the most common methods of producing tungsten oxide. The method is to react tungsten solution with acid to produce a tungsten oxide residue and the corresponding salt. The specific steps are as follows:

The tungsten solution is reacted with acids (such as hydrochloric acid, nitric acid, hydrochloric acid, hydrochloric acid sulfuric acid, etc.) to adjust the pH value of the solution to keep it within a certain range.

The reaction solution is filtered to remove insoluble matter and impurities.

The filtered solution is evaporated and concentrated to precipitate the tungsten oxide.

The tungsten oxide precipitates are washed, dried, and crushed to obtain the required tungsten oxide products.

It should be noted that the chemical reaction conditions and the control of pH value have an important impact on the purity and quality of tungsten oxide. In addition, the method requires the use of a large amount of acid and tungstate raw materials, and the cost is high, not suitable for large-scale production.

Second, physical law

The physical method is another method of producing tungsten oxide, which is usually carried out at high temperatures. The method is to oxidize tungsten powder or tungsten strip at high temperatures to obtain tungsten oxide. The specific steps are as follows:

The tungsten powder or tungsten strip is put into a high-temperature furnace for oxidation treatment, and the temperature is usually above 800 ° C.

At high temperatures, tungsten powder or tungsten strips are gradually oxidized to produce tungsten oxide gas.

The tungsten oxide gas is collected and cooled to obtain the required tungsten oxide product.

It should be noted that the temperature and oxidation time of the physical method have an important impact on the purity and quality of tungsten oxide. In addition, this method requires the use of high-temperature equipment for oxidation treatment and collection and other processes, which have high energy consumption. However, the physical method has the advantages of a simple process and low cost, so it is widely used in industry.
