Overview of ISO grade MoS2 98.5%min molybdenum disulfide powder for lubricant
Metal powder is a common form of metal that has been processed into fine particles, ranging from a few micrometers to over 100 microns in diameter. It plays a crucial role in various industrial applications due to its unique properties and versatility.
Features of ISO grade MoS2 98.5%min molybdenum disulfide powder for lubricant
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 ISO grade MoS2 98.5%min molybdenum disulfide powder for lubricant
Molybdenum disulfide (MoS2), also known as molygraphite or MoS, is a naturally occurring compound with exceptional lubrication properties, making it a popular choice in various industries, particularly for high-temperature and high-pressure applications. ISO grade MoS2 powders, specifically those with a minimum 98.5% purity, are of great significance due to their superior performance characteristics.
ISO grading system for MoS2 powder refers to the international standard set by the International Organization for Standardization (ISO) to ensure consistent quality and compatibility across different manufacturers. The 98.5% minimum purity indicates that the powder contains at least this proportion of molybdenum disulfide, with the remaining 1.5% being impurities, which are typically composed of trace elements and very small amounts of other compounds.
The key parameters of ISO grade 98.5% MoS2 powder for lubricants include:
1. Particle Size Distribution: This refers to the range of particle sizes present in the powder. For lubricant-grade MoS2, a narrow and uniform distribution is desired, ensuring consistent film formation and effective lubrication. The typical size range may vary from sub-micron to a few micrometers, depending on the application requirements.
2. Purity: As mentioned, the minimum purity of 98.5% ensures minimal contamination, which is crucial for maintaining the lubricating properties and avoiding potential wear on machinery.
3. Crystal Structure: MoS2 forms in two primary crystal structures, hexagonal and monoclinic. High-quality lubricant-grade MoS2 usually has a predominantly hexagonal structure, providing better lubricity and resistance to oxidation.
4. Surface Finish: A smooth surface finish on the particles promotes better adhesion and reduces friction, enhancing the overall performance of the lubricant.
5. Thermal Stability: Molybdenum disulfide is known for its exceptional thermal stability, allowing it to maintain its lubricating properties under high temperatures. The ISO grade 98.5% powder should demonstrate this property to withstand operating conditions without degradation.
6. Compatibility: The powder must be compatible with the base lubricants and other additives used in various industrial applications, ensuring a homogeneous mixture and preventing settling or agglomeration.
7. Resistant to Wear: High-purity MoS2 has excellent wear resistance, protecting metal surfaces from damage and extending the lifespan of equipment.
8. Oxidation Resistance: The ISO grade 98.5% powder should exhibit low oxidation rates, preventing the formation of abrasive oxides that can compromise lubrication.
In conclusion, ISO grade 98.5% molybdenum disulfide powder for lubricants is a premium product characterized by its high purity, well-defined particle size distribution, and desirable physical and chemical properties. These attributes make it an ideal choice for demanding applications where reliable lubrication and longevity are critical. By adhering to the ISO standards, manufacturers ensure that their products meet the industry’s expectations for performance, reliability, and consistency.
