Parameters of Factory supply 99% WO3 CAS 1314-35-8 Tungsten Trioxide / TUNGSTEN OXIDE / Tungsten(VI) oxide
Tungsten Trioxide, also known as Tungsten Oxide or Tungsten(VI) oxide, is a chemical compound with the chemical formulaWO3 and the CAS number 1314-35-8. It is an inorganic substance that plays a significant role in various industries due to its exceptional properties, including high thermal stability, electrical resistance, and chemical inertness.
Manufactured by factories, tungsten trioxide is primarily derived from tungsten metal through a refining process. The starting material is tungsten sponge, which is obtained from tungsten ores like wolframite or scheelite. This sponge undergoes a series of purification steps, including smelting, leaching, and chemical reactions, to isolate tungsten and form tungsten trioxide.
The final product, 99% pure tungsten trioxide, is a white to off-white crystalline solid. Its structure consists of trigonal planar oxygen atoms surrounding a central tungsten atom, forming a network of corner-sharing octahedra. This unique crystal lattice structure imparts tungsten trioxide with remarkable properties such as high melting point (around 2,795°C), low solubility in water, and excellent chemical stability, making it resistant to most acids and bases.
In the electronics industry, tungsten trioxide finds applications in thin-film transistors and integrated circuits due to its excellent electrical conductivity and high dielectric strength. It is also used in the production of high-k dielectrics for semiconductor devices, which help to reduce power consumption and improve device performance.
In ceramic manufacturing, tungsten trioxide is a key ingredient in the production of advanced ceramics, such as tungsten carbide and tungsten-rhenium alloys, used in cutting tools, wear-resistant coatings, and even rocket nozzles. Its hardness and wear resistance make it ideal for these demanding applications.
Tungsten trioxide is also employed in the glass and optical industries as a refractory material, improving the glass’s heat resistance and clarity. It can be incorporated into glass formulations to create special properties like infrared transparency or enhanced durability.
In the chemical sector, tungsten trioxide serves as a catalyst in various chemical reactions, particularly in the production of polyurethanes, adhesives, and other organic compounds. Its ability to promote oxidative reactions makes it a valuable addition to these processes.
Environmental applications include tungsten trioxide as a component in air pollution control systems, where it can catalyze the conversion of harmful gases into less harmful substances. Additionally, it is used in the production of water treatment chemicals, such as flocculants, to aid in the purification process.
In summary, tungsten trioxide, with its CAS number 1314-35-8, is a versatile chemical compound with a wide range of industrial applications. Its high purity, unique structural features, and exceptional properties make it an essential material in various sectors, from electronics to environmental remediation. The manufacturing process ensures consistent quality and reliability, positioning tungsten trioxide as a critical raw material in modern technology and manufacturing.
