Tungsten Oxide

London Chemicals & Resources Ltd (LCR) is an international distributor, stockist and supplier of industrial inorganic chemicals including Tungsten Oxide.

Tungsten Oxide, like its elemental form, possesses some unique properties that make it valuable in several industries. It is a compound of tungsten and oxygen, and its most common form is yellow tungsten oxide, often used in the production of tungsten metal for various applications[1].

One of the notable properties of Tungsten Oxide is its malleability coupled with a high melting point, density, and hardness[1]. This makes it particularly useful in industries that require materials that can withstand extreme conditions. Its conductivity also makes it an excellent choice for electronic applications[1].

Tungsten Oxide is widely used in the metal-working, mining, and petroleum industries, primarily due to its immense hardness[2]. It is produced by mixing tungsten powder and carbon, creating a compound known as tungsten carbide[2]. This material is critical for manufacturing cutting tools and wear-resistant coatings, proving its importance in heavy-duty industrial applications[2].

In the electronics industry, Tungsten Oxide finds use in the production of electrodes and heating elements, thanks to its high melting point and stability[2]. It is also a key material in making light bulb filaments, demonstrating its versatility[2].

The military also benefits from the properties of Tungsten Oxide, utilizing it in various applications where strength and durability are paramount[2]. It is also used in the creation of heavy metal alloys, reinforcing the strength and durability of other materials[2].

The production of Tungsten Oxide often involves the use of low-cost raw materials, contributing to the simplicity and cost-effectiveness of the process[3]. This method also yields fine particles, which are desirable in many industrial applications[3].

In conclusion, Tungsten Oxide, with its unique properties of hardness, stability, high melting point, and conductivity, plays a vital role in various industries. From metal-working and mining to electronics and the military, its applications are wide-ranging and impactful. Its production method also aligns with industry demands for cost-effectiveness and fine particle production, making it a truly significant material in the industrial world.

What Is Tungsten Oxide?

Tungsten(III) oxide (W2O3) is a compound of tungsten and oxygen. It has been reported (2006) as being grown as a thin film by atomic layer deposition at temperatures between 140 and 240 °C using W2(N(CH3)2)6 as a precursor. It is not referred to in major textbooks. Some older literature refers to the compound W2O3 but as the atomic weight of tungsten was believed at the time to be 92, i.e., approximately half the modern accepted value of 183.84, the compound actually being referred to was WO3


Tungsten(III) oxide is used in various types of infrared absorbing coatings and foils.

We can help to supply:

  •  APT
  •  Sodium Tungstate
  •  Calcium Tungstate
  •  Tungsten Trioxide

Tungsten Trioxide is typically available in most volumes. Ultra-high purity, high purity, submicron and nanopowder forms may be considered.
