1.Performance and use

Molybdenum disulfide is a solid powder made from natural molybdenum concentrate powder by changing the molecular structure after chemical purification. This product is black slightly silver gray, with metallic luster, slippery to the touch, insoluble in water. The product has the advantages of good dispersibility and non-bonding, and can be added in various greases to form a colloidal state that will never bond, and can increase the lubricity and extreme pressure of grease. It is also suitable for high temperature, high pressure, high speed and high load mechanical working condition, prolonging the life of the equipment.

Molybdenum disulfide is an important solid lubricant, known as the “king of advanced solid lubricants”, especially suitable for high temperature and high pressure. It is also antimagnetic and can be used as a linear photoelectric conductor and a semiconductor displaying P-type or N-type electrical conductivity, with the role of rectification and energy conversion. Molybdenum disulfide can also be used as a catalyst for dehydrogenation of complex hydrocarbons.
