Parameters of Factory Supply Tungsten trioxide WO3 / Tungsten(VI) oxide CAS 1314-35-8
Tungsten Trioxide (WO3), also known as Tungsten(VI) oxide, is a chemical compound with the molecular formula WO3 and the CAS number 1314-35-8. It belongs to the group of inorganic compounds and holds significant importance in various industrial applications due to its unique properties.
Tungsten, a chemical element with the symbol W and atomic number 74, is a hard, dense, and corrosion-resistant metal. When combined with oxygen, it forms tungsten trioxide, which exhibits a crystalline structure, typically in the form of a black or gray powder. The compound is amphoteric, meaning it can react with both acids and bases, making it versatile in chemical reactions.
One of the key features of WO3 is its high refractory properties. It has an exceptional melting point of around 3,422 degrees Celsius (6,232 degrees Fahrenheit), which makes it ideal for applications where resistance to high temperatures is crucial. This property makes tungsten trioxide a popular choice in industries like electronics, where it is used as a protective coating for heating elements and semiconductor devices.
In the field of ceramics, tungsten trioxide is employed as a raw material in the production of high-performance ceramics, such as tungsten carbide and tungsten-bronze alloys. These materials exhibit excellent mechanical strength, wear resistance, and thermal stability, making them suitable for applications in cutting tools, wear-resistant coatings, and turbine blades.
Tungsten trioxide also plays a role in the production of pigments, where it is used as a black or blue colorant in various paint, ink, and ceramic glazes. Its opacity and lightfastness contribute to the durability and visual appeal of the final product.
Moreover, tungsten trioxide is involved in the purification of air and water treatment processes. It acts as a catalyst in the removal of sulfur dioxide (SO2) from flue gases, contributing to environmental sustainability by reducing acid rain formation. It can also be used as a flocculant in water treatment plants to facilitate the separation of suspended particles.
In the pharmaceutical industry, tungsten trioxide is occasionally utilized in the formulation of certain drugs, although its use is limited due to potential toxicity concerns when administered internally. However, it can be employed in the manufacturing of medical devices and implants that require high thermal stability and resistance to wear.
Lastly, tungsten trioxide is a research topic of interest in the field of nanotechnology. Nanostructured tungsten oxide particles exhibit unique electronic, optical, and catalytic properties, which have potential applications in areas like solar cells, sensors, and energy storage devices.
In summary, tungsten trioxide, with its exceptional thermal stability, refractory properties, and diverse applications, is a vital material in various sectors. Its unique characteristics make it an essential component in the production of high-performance ceramics, pigments, environmental remediation systems, and even emerging technologies. Despite its challenges, the study and utilization of tungsten trioxide continue to drive innovation and advancements across numerous industries.
