Description
Molybdenum Disulfide (MoS₂) Micron Powder, Purity: 99.9+%, Size: 325 mesh
Molybdenum Disulfide (MoS₂) Micron Powder is a dark gray to black solid lubricant with excellent thermal stability, high chemical inertness, and outstanding lubricity, even in vacuum and extreme environments. With a particle size of 325 mesh and ultra-high purity of 99.9+%, this powder is ideal for high-performance industrial applications requiring reduced friction, wear resistance, and long-term stability.
Due to its layered crystal structure, MoS₂ exhibits low shear strength between planes, making it a powerful solid lubricant. It remains stable in high-vacuum environments and resists degradation under high load, making it suitable for aerospace, automotive, and electronics industries.
