Parameters of MoS2 powder CAS 1317-33-5 molybdenum sulfide powder
Molybdenum disulfide (MoS2) is a fascinating inorganic compound with the chemical formula MoS2 and the CAS number 1317-33-5. It is an essential material in various scientific, industrial, and technological applications due to its unique properties. As a powder form, it exhibits remarkable characteristics that make it stand out among other materials.
Molybdenum sulfide is a layered crystal structure, consisting of molybdenum atoms sandwiched between layers of sulfur atoms, forming a hexagonal lattice. Each molybdenum atom is bonded to six sulfur atoms, creating a strong covalent bond. The powder form is composed of these thin, platelet-like structures that are exfoliated from larger crystals, providing high surface area and versatility.
One of MoS2’s most notable features is its exceptional thermal stability. It has a high melting point, around 2623°C, which makes it resistant to heat and suitable for applications requiring thermal resistance. Additionally, it possesses excellent electrical conductivity, especially in its two-dimensional form, where it acts as a semiconductor with tunable bandgap. This property makes it attractive for use in electronic devices, such as transistors and sensors.
MoS2 is also known for its lubricious nature, often referred to as “white moly” due to its lustrous appearance. Its low friction coefficient and self-lubricating properties make it a popular choice in bearings, gears, and other mechanical components that require minimal wear. The powder form facilitates easy application and provides a smooth, long-lasting lubrication layer.
In the field of energy storage, MoS2 finds significant use as a cathode material in lithium-ion batteries. Its high theoretical capacity, good rate capability, and environmental stability make it a promising candidate for next-generation battery technologies. Furthermore, the layered structure of MoS2 allows for efficient lithium intercalation and de-intercalation, contributing to enhanced battery performance.
Another intriguing aspect of MoS2 is its potential for optoelectronic applications. It exhibits photoluminescence properties, which means it can emit light when excited by an external source. This property is being explored for use in light-emitting diodes (LEDs), solar cells, and even as a component in quantum dot-based displays.
In the realm of nanotechnology, MoS2 is a key component in the development of 2D materials, such as graphene and transition metal dichalcogenides (TMDs). These materials hold immense promise for applications in electronics, optoelectronics, and even flexible and wearable devices due to their extraordinary mechanical, electronic, and optical properties.
However, despite its numerous benefits, the synthesis of high-quality MoS2 powder can be challenging. Traditional methods, like chemical vapor deposition (CVD) or hydrothermal synthesis, may result in impurities or defects in the crystal structure. Therefore, ongoing research focuses on optimizing synthesis techniques to obtain defect-free, large-scale production of MoS2 powders.
In conclusion, molybdenum sulfide (CAS 1317-33-5) powder, with its exceptional thermal stability, electrical conductivity, lubricity, and potential applications in energy storage and optoelectronics, is a versatile material with a promising future. As researchers continue to unlock its full potential, we can expect to see MoS2 playing a pivotal role in various industries, revolutionizing the way we design and engineer modern technologies.
