Molybdenum Disulfide Technical Fine Grade

Introduction

 

Molybdenum Disulfide Technical Fine Grade is a diamagnetic compound with semiconducting properties. The Mo-S facets in molybdenum disulfide are quite large, the specific surface area is large, the inner layer is a strong covalent bond, and the interlayer is a weak van der Waals force, The layers are easily peeled off, with good anisotropy and low friction coefficient.

Molybdenum Disulfide Technical Fine Grade 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 Technical Fine Grade can be lubricated for a long time in the air below 350 ℃.

With more than ten years of research and development experience, it can provide an annual output of 550 tons of Molybdenum Disulfide Technical Fine Grade as a patented technology product.

Molybdenum Disulfide Technical Fine Grade is a lubricant grade of molybdenum disulfide (MoS₂). Typical MoS₂ content (calculated average) is 98.5%.

 

Chemical Specifications of Molybdenum Disulfide Technical Fine Grade：

	Maximum % by wt
Acid Insoluble	0.50
Iron	0.25
Molybdenum Trioxide	0.10
Water	0.20
Oil	0.40
Carbon	0.50
Acid Number	0.50

 
*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.
