Molybdenum

Molybdenum (Mo) is a silvery-white, hard, transition metal with an atomic number of 42 and an atomic mass of 95.95 u. It features a high melting point of 2623°C (4753°F), a boiling point of 4639°C (8382°F), and a density of 10.28 g/cm³. Molybdenum has a body-centered cubic crystal structure and is characterized by its excellent strength at high temperatures, good thermal and electrical conductivity, and low thermal expansion.

In electronics, molybdenum's properties make it valuable for various applications. Its high thermal conductivity enables it to dissipate heat in electrical devices, while its strength and stability at elevated temperatures are essential for making electrical contacts, filaments, and other components that operate under intense conditions.

Molybdenum is also used in thin-film transistors (TFTs) commonly found in LCD displays, where it serves as the gate electrode, providing durability and stability. Additionally, in semiconductor manufacturing, molybdenum's good electrical conductivity and high melting point make it an excellent choice for use in the production of integrated circuits and as a material for sputtering targets in physical vapor deposition (PVD) processes.

Furthermore, because of its compatibility with other metals and semiconductor materials, molybdenum finds use in the production of electrodes, interconnects, and barrier layers within various electronic components, enhancing performance and longevity. Its application in electronics is integral to the advancement of technology, where reliable and efficient materials are constantly in demand.
