Parameters of Molybdenum Superfine 3um To 5um Molybdenum Disulfide MoS2 Powder For Lubrication Nanoparticle MoS2
Molybdenum disulfide (MoS2), also known as molybdenum sulfide, is a popular material for various applications due to its unique properties, such as lubrication, electrical conductivity, and thermal stability. When it comes to superfine particles with a size range of 3-5 micrometers (μm) for lubrication purposes, the following parameters typically describe this nanostructured MoS2:
1. Particle Size Distribution: The 3-5 μm range indicates that the powder consists of particles with diameters falling within this interval. This size is considered submicron or nanoscale, which enhances its surface area and reactivity.
2. Specific Surface Area: Due to the small particle size, the specific surface area of this MoS2 is relatively high, typically in the range of 10-100 m²/g. This increased surface area allows for better adhesion and improved lubrication performance.
3. Crystal Structure: MoS2 is usually in the form of a hexagonal layered structure, commonly known as the 2H phase. Each layer consists of a molybdenum atom sandwiched between two sulfur atoms, forming a trigonal prismatic geometry.
4. Chemical Composition: Pure molybdenum disulfide is composed of 42.9% molybdenum (Mo) and 57.1% sulfur (S) by weight.
5. Thermal Stability: At elevated temperatures, MoS2 maintains its integrity up to around 650-800°C, making it suitable for applications where heat resistance is crucial.
6. Electrical Conductivity: Depending on the crystal structure and impurities, MoS2 can exhibit varying electrical conductivity. In its pure form, it is an insulator, but doped forms can become semiconducting or even metallic.
7. Lubrication Properties: As a lubricant, MoS2 offers low friction coefficients, wear resistance, and excellent chemical stability. It can form a protective film on moving surfaces, reducing wear and tear.
8. Nanostructure: Being a nanoparticle, the material exhibits quantum confinement effects, leading to enhanced mechanical, optical, and electronic properties compared to bulk MoS2.
9. Dispersion: The superfine particles should have good dispersion in solvents or lubricants to ensure even application.
10. Purity: High purity MoS2 powders typically have a low impurity content, ensuring minimal contamination during use.
These parameters are subject to slight variations depending on the specific manufacturing process and the supplier. It’s essential to consult the manufacturer’s specifications for detailed information on the properties of the particular MoS2 powder you’re interested in.
