Description of Molybdenum Disulfide Powder

Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is mos. The compound is classified as a transition metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum. is relatively unreactive. It is unaffected by dilute acids and oxygen. In appearance and feel, molybdenum disulfide is similar to graphite.

It is widely used as a dry lubricant because of its low friction and robustness. Bulk mos. is a diamagnetic, indirect bandgap semiconductor similar to silicon, with a bandgap MoS2 is naturally found as either molybdenite, a crystalline mineral, or jordanite, a rare low-temperature form of molybdenite. Molybdenite ore is processed by flotation to give relatively pure Mos. the main contaminant is carbon. MOs also arises by thermal treatment of virtually all molybdenum compounds with hydrogen sulfide or elemental sulfur and can be produced by metathesis reactions from molybdenum pentachloride.

MoS2 excels as a lubricating material (see below) due to its layered structure and low coefficient of friction. Interlayer sliding dissipates energy when shear stress is applied to the material. Extensive work has been performed to characterize the coefficient of friction and shear strength of MoS2 in various atmospheres.

The shear strength of MoS2 increases as the coefficient of friction increases. This property is called superlubricity. At ambient conditions, the coefficient of friction for MoS2 was determined to be 0.150, with a corresponding estimated shear strength of 56.0 MPa. Direct methods of measuring the shear strength indicate that the value is closer to the wear resistance of MoS2 in lubricating applications can be increased by doping MoS2 with chromium.

Flakes thinner than 5 layers undergo homogenous bending and rippling, while flakes around 10 layers are thickly delaminated through interlayer sliding. Flakes with more than 20 layers exhibited a kinking mechanism during micromechanical cleavage. The cleavage of these flakes was also determined to be reversible due to the nature of van der Waals bonding.
