As the main component of molybdenite, molybdenum disulfide is black solid powder with metallic luster. Molybdenum disulfide has stable properties. Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid. Generally, molybdenum disulfide is insoluble in other acids, alkalis and organic solvents, but molybdenum disulfide is soluble in aqua regia and boiled concentrated sulfuric acid.
Molybdenum Disulfide is a lubricant grade of molybdenum disulfide (MoS2) available in three grades-Technical, Technical Fechnical Fine, and Super Fine.Typical MoS2 content (calculated average) is 98.5%.
Molybdenum Disulfide is a good solid lubricant that can be lubricated in a vacuum or air environment for a long time. The friction coefficient is relatively low, and Molybdenum Disulfide can be lubricated for a long time in the air below 350℃.
With more than ten years of R&D experience, it can provide an annual output of 1,000 tons of Molybdenum Disulfide as a patented technology product.

*Acid number is determined at time of production. Prolonged storage will result in slight oxidation,which will produce an increase in acid number.The smaller particle size grades are more susceptible to surface oxidation.Acid number is expressed as an absolute value and is the mg of KOH required to neutralize the acid in a one-gram sample.

On January 30, 2023, molybdenum price rose by more than 20% in a single day, breaking a new 17-year high. Molybdenum is known as the "war metal", "steel warrior". Molybdenum is valued by more and more countries. China is the world's richest country in molybdenum resources, with reserves of 4.3 million tons, followed by the United States (2.7 million tons) and Chile (1.8 million tons), which acco...more
