Parameters of Great Molybdenum disulfide MoS2 powder CAS 1317-33-5 supply
Molybdenum disulfide (MoS2), also known as molybdenite, is a layered transition metal dichalcogenide with the chemical formula MoS2 and the CAS number 1317-33-5. It is a fascinating material that has garnered significant attention due to its unique properties and diverse applications across various industries.
The structure of MoS2 is composed of a hexagonal lattice arrangement, where molybdenum atoms are sandwiched between layers of sulfur atoms. Each layer is held together by weak van der Waals forces, which allows for easy exfoliation into atomically thin sheets, often referred to as molybdenum disulfide nanosheets or MoS2 flakes. This layered nature gives rise to its extraordinary mechanical, electrical, and thermal properties.
In terms of physical appearance, MoS2 powder typically appears as a yellow or brownish-black solid, with a shiny luster when freshly prepared. The particles are generally in the submicron range, providing a high surface area, which is advantageous for many applications. Its bulk form exhibits a Mohs hardness of around 6, making it relatively durable and resistant to scratching.
Molybdenum disulfide is an intrinsic semiconductor, with a bandgap of approximately 1.2 to 1.8 electron volts, depending on the crystal quality and thickness. This bandgap makes it suitable for optoelectronic devices such as photodetectors, solar cells, and light-emitting diodes (LEDs). The material’s tunable electronic properties, including its ability to be doped with other elements, enable its use in various electronic devices.
MoS2 is also renowned for its exceptional thermal conductivity, which is higher than many metals, making it a promising candidate for heat management in high-power electronics and thermoelectric applications. Its thermal stability and low coefficient of thermal expansion further contribute to its thermal performance.
In the field of lubrication, MoS2 is widely used as a high-performance solid lubricant, known as molybdenum disulfide powder. It forms a self-lubricating film when subjected to friction, reducing wear and tear and extending the lifespan of machinery. Additionally, it exhibits excellent anti-corrosion properties, protecting surfaces from corrosion in harsh environments.
Biomedical applications are another area where MoS2 finds extensive use. Due to its biocompatibility and non-toxicity, it has been explored for drug delivery systems, tissue engineering, and as a scaffold material for cell growth. The material’s unique electronic properties also make it suitable for biosensing applications, detecting biomolecules with high sensitivity and selectivity.
In recent years, MoS2 has garnered attention in the field of energy storage, particularly in lithium-ion batteries and supercapacitors. Its large surface area and excellent electrical conductivity make it an ideal electrode material, improving the battery’s performance and capacity.
In summary, Molybdenum disulfide (CAS 1317-33-5) is a versatile material with exceptional properties that make it a sought-after component in numerous industrial sectors. Its layered structure, electrical conductivity, thermal stability, and biocompatibility open up a wide range of possibilities for applications in electronics, energy storage, lubrication, and even medicine. As research continues to uncover new ways to harness its potential, the future of MoS2 holds immense promise for innovation and technological advancements.
