Features of High purity 99.99% 99.9% Ultrafine 100nm Molybdenum disulfide nano MoS2 powder
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of High purity 99.99% 99.9% Ultrafine 100nm Molybdenum disulfide nano MoS2 powder
Molybdenum disulfide (MoS2), a renowned material in the field of nanotechnology, is a transition metal dichalcogenide with exceptional properties that make it highly sought after for various applications. The high purity grade you mentioned, specifically 99.99% and 99.9%, indicates an extremely pure form of the compound, minimizing impurities and ensuring optimal performance.
Ultrafine particles in the range of 100 nanometers (100nm) are of particular interest due to their unique characteristics. At this nanoscale, MoS2 exhibits a large surface area-to-volume ratio, which significantly enhances its catalytic, electronic, and optical properties. The reduced particle size allows for better interaction with surrounding molecules, leading to improved efficiency in applications such as energy storage, lubricants, and even electronics.
In terms of physical appearance, the MoS2 nano powder appears as a fine, pale yellow or brownish-black powder, depending on the degree of crystallinity and impurities. It has a layered structure, with each layer consisting of a molybdenum atom sandwiched between two sulfur atoms, forming a hexagonal lattice. This structure gives rise to its characteristic lamellar morphology when observed under a microscope.
The chemical stability of MoS2 makes it resistant to corrosion and oxidation, making it suitable for use in harsh environments. It is known for its excellent thermal conductivity, which is essential in heat dissipation and thermal management systems. Additionally, its semiconducting nature, with a bandgap that can be tuned by controlling particle size, makes it a promising material for optoelectronic devices like solar cells and light-emitting diodes.
In the field of lubrication, ultrafine MoS2 is used as a high-performance additive due to its self-lubricating properties and ability to reduce friction and wear. It finds application in aerospace, automotive, and industrial machinery, where friction reduction is critical for efficiency and longevity.
Furthermore, MoS2 is gaining traction in the realm of energy storage, particularly in lithium-ion batteries. Its large surface area and catalytic activity make it an ideal candidate for cathode materials, contributing to enhanced battery performance in terms of capacity and cycle life.
In summary, high purity 99.99% and 99.9% ultrafine 100nm MoS2 nano powder offers exceptional properties such as large surface area, tunable bandgap, chemical stability, and self-lubrication. These features make it a versatile material with potential applications in various sectors, including electronics, energy storage, lubrication, and more. Its unique characteristics make it a valuable addition to the ever-evolving world of nanotechnology.
