CAS 7440-33-7
:Tungsten
Description:
Tungsten, with the CAS number 7440-33-7, is a transition metal known for its remarkable properties. It has the highest melting point of all elements, making it exceptionally valuable in high-temperature applications. Tungsten is characterized by its dense, hard, and brittle nature, with a metallic luster. It exhibits excellent conductivity for both heat and electricity, which makes it suitable for various electrical applications. Chemically, tungsten is relatively inert, resisting corrosion and oxidation at room temperature, although it can react with halogens and acids at elevated temperatures. Its compounds, such as tungsten carbide, are widely used in cutting tools and abrasives due to their hardness. Tungsten is also utilized in the production of filaments for light bulbs and in the aerospace and military industries for its strength and durability. Additionally, tungsten has a significant role in the production of alloys, enhancing the properties of materials used in demanding environments. Overall, tungsten's unique combination of physical and chemical properties makes it an essential material in various industrial applications.

Tungsten metal powder
CAS:Controlled Product<p>Tungsten metal powder is a reactive chemical element that has an atomic number of 74 and an atomic weight of 183.85. It is used in the production of light bulbs, vacuum tubes, and filaments for electric lamps. Tungsten metal powder reacts with water vapor to produce hydrogen gas and tungsten oxide, which can be detected by kinetic energy analysis. Tungsten metal powder is also used as a catalyst in the laboratory during reactions involving molybdenum or dimethyl fumarate. The reaction mechanism has been elucidated through x-ray crystal structures and electrochemical impedance spectroscopy (EIS). Tungsten metal powder has a high chemical stability, making it useful for analytical methods such as laser ablation mass spectrometry (LA-MS) and EIS analysis.</p>Purity:Min. 95%
