Parameters of CAS 12136-78-6 Molybdenum Silicide powder MoSi2 powder
Molybdenum silicide, also known as MoSi2 or MoSi in chemical notation CAS 12136-78-6, is a fascinating compound that combines the elements molybdenum (Mo) and silicon (Si). This binary compound finds extensive applications due to its unique properties, which make it a versatile material in various industries.
Molybdenum silicide is formed through a combination of molybdenum atoms and silicon atoms, forming a metallic lattice structure. At room temperature, it exists in a hexagonal crystal structure, commonly referred to as α-MoSi2. The compound exhibits excellent high-temperature stability, with a melting point around 2,200°C, making it an ideal material for applications where resistance to heat is crucial.
One of the key features of MoSi2 is its exceptional thermal conductivity. It has a higher thermal conductivity than many metals, which allows it to dissipate heat effectively. This property is highly sought after in electronic components, such as heat sinks and thermoelectric generators, where efficient heat management is vital to prevent overheating and maintain optimal performance.
Another remarkable aspect of molybdenum silicide is its low coefficient of thermal expansion, which means it expands less under temperature changes compared to conventional materials. This makes it suitable for applications like high-precision engineering components, aerospace parts, and semiconductor devices, where dimensional stability is critical.
Molybdenum silicide is also known for its high electrical resistivity, which varies depending on the stoichiometry. The compound can be doped with other elements to tailor its electrical properties, making it useful in both insulating and semiconducting applications. It finds application in microelectronics, particularly in semiconductor contacts, due to its ability to form smooth interfaces with other materials.
Moreover, MoSi2 possesses good mechanical strength and wear resistance, which makes it suitable for use in wear-resistant coatings, cutting tools, and bearings. Its hardness, coupled with its ability to withstand elevated temperatures, makes it ideal for harsh industrial environments where durability is paramount.
In the field of energy, molybdenum silicide is used in thermocouples, where its high Seebeck coefficient enables efficient conversion of temperature differences into electrical signals. Additionally, it is investigated for potential applications in fuel cells, as a catalyst support material, due to its stability at high temperatures.
In conclusion, CAS 12136-78-6 Molybdenum Silicide (MoSi2) is a valuable material with unique properties that make it suitable for a wide range of applications. Its high thermal conductivity, low thermal expansion, electrical versatility, and mechanical strength contribute to its widespread use in industries such as electronics, aerospace, automotive, and energy. As researchers continue to explore new ways to harness its potential, molybdenum silicide is poised to play an increasingly important role in technological advancements in the future.
