molybdööni

Molybdööni is the Finnish word for molybdenum, a chemical element with the symbol Mo and atomic number 42. It is a silvery-white, hard, and strong metal that is highly resistant to corrosion. Molybdenum is not found in nature in its metallic form but rather in various oxidation states in minerals, most commonly as molybdenite.

The primary uses of molybdenum are in the steel industry, where it is added as an alloying element to produce various steels, including stainless steel, high-speed steel, and tool steel. These alloys exhibit enhanced strength, hardness, toughness, and resistance to wear and corrosion, making them suitable for a wide range of applications such as automotive parts, aerospace components, and industrial machinery. Molybdenum is also used in the production of superalloys, which are critical for high-temperature applications in jet engines and gas turbines.

Beyond its metallurgical applications, molybdenum compounds have important roles in other areas. Molybdenum is an essential trace element for many organisms, playing a crucial role in enzyme function in both plants and animals. Molybdates are used as corrosion inhibitors, pigments, and catalysts in chemical processes. For example, ammonium molybdate is used in analytical chemistry and as a nutrient in fertilizers. Molybdenum disulfide (MoS2) is a notable lubricant due to its layered structure, which allows for low friction between layers.
