Molybdenum Disulfide MoS2:

Molybdenum diulfide (Moly) is a.

Molybdenite is a component.

Molybdenum disulfide is a powder.

It is a black solid powder with metallic luster.

The chemical formula for molybdenum sulfide

It is called MoS2.

Molybdenum disulfide melting point

The temperature is 1185 degC.

Molybdenum disulfide density

Mohs hardness is 1.01.5. Mohs Hardness: 1.01.5. At 1370degC the decomposition process begins. It decomposes at 1600degC into molybdenum metallic and sulfur. At 315degC it starts to oxidize in the air. As the temperature increases, the oxidation reactions accelerate.

Moly Disulfide

Insoluble in concentrated sulfuric and dilute acid, water or dilute acid. It is not soluble in alkalis or organic solvents. However, it is soluble with aqua regia, boiling concentrated sulfuric acids and other acids. At 400, it is slowly oxidized to produce molybdenum Trioxide.

Test the molybdenum reagent with 2MoS2+7O2- 2 MoO3+4SO2. After treating the product with sodium hydroxide, or potassium hydroxide, (the goal is to convert molybdenum trioxide into molybdate), the titanium iron solution is then added dropwise. This method is sensitive enough to detect traces of molybdate. The solution will not turn golden yellow if no molybdenum dioxide is generated. This is because molybdenum disulfide reacts with either sodium or potassium hydroxide.


Can react with chloride when heated to form molybdenum penteachloride

2 MoS2+ 7 Cl2- 2 MoCl5+ 2 S2Cl2

LixMoS2 (intercalation compound or interlayer compound) is the result of a controlled reaction between molybdenum disulfide, alkyl lithium and a controllable amount of oxygen. LiMoS2 will be formed if the reaction is with butyllithium.

Molybdenum Disulfide is a disulfide with a high sulfur content. This active sulfur can easily cause copper to corrode. In many books and articles on lubricant add-ons, it is mentioned. When parts made of copper or its alloys are to be lubricated it is not difficult to use molybdenum-disulfide lubricating agents, but it is also possible to add copper corrosion inhibitors.

Molybdenum Disulfide MoS2 Poudre


Natural law

MoS2 may be produced by natural methods, such as the molybdenite concentration purification method. The molybdenite concentrator is subjected to physical and chemical reactions to remove acid-insoluble materials, including SiO2, Fe, and Cu. Ca, Pb and impurities such as copper are refined further to get nano-MoS2. Although the purity of nano-MoS2 made by the natural process is low, purification technology still needs to be improved. If the temperature of the atmosphere is less than 400 degrees, the most expensive MoS2 should be used. It has a lubricating capability below 1300 and is recommended to use cost-based MoS2.

Chemical synthesis

Synthetic method is able to prepare sulfides which are high in purity, have less impurities, finer particles, and meet various functional requirements. Synthetic methods have always been used to produce nano sulfides. There are a number of methods to produce nano-MoS2, for example, the thermal decomposition of ammonium, the hydrogen sulfide, or sulfur reduction method, the high-energy milling, carbon nanotube confinement, hydrothermal method, physical and chemical method combinations, etc.

Molybdenum Diulfide:

It is diamagnetic and can be used to convert semiconductors or photoconductors that have a P-type of N-type conductivity.

Molybdenum isothiocyanate can be synthesized for use as a dehydrogenation catalyst.

Molybdenum diulfide has also been referred to as “the King of Advanced Solid Lubricants”.

Molybdenum diulfide is an inorganic powder derived from molybdenum concentrations that have been chemically purified through a change in the molecule structure.

Molybdenum Disulfide disperses well and is not required to be added. It is added to greases as a colloidal phase and does not replace the original grease.

Molybdenum diulfide also extends the life span of equipment by being suitable for conditions such as high temperatures, pressure, viscosity or high loads.

Molybdenum Disulfide is primarily used as a friction product to reduce friction and combustion loss at low temperatures. It also increases friction at higher temperatures. The friction material is easily volatilized.

Anti-friction: Because the size of the disulfide particle formed by supersonic jet milling can reach 325-2500 Mesh, the particle hardness can be up to 1-1.5 and the friction coefficient can be 0.05-0.1 it can also used in friction materials for the anti-friction effects;

Molybdenum dioxide is not conductive. Molybdenum triosulfide or molybdenum triioxide can increase friction. When the temperature of a friction material increases sharply because of friction, the molybdenum dioxide particles that are shrinking gradually heat up, and then expand. This increases friction in an axial direction.

Antioxidant : Molybdenum Disulfide, obtained from a comprehensive chemical reaction, has a pH of 7-8 (slightly alkaline). It is a coating that protects other materials from oxidation.

Store Molybdenum Disulfide MoS2 in the following conditions:

Molybdenum Disulfide MoS2 Pulp will be affected by dampness, so it is important to store the powder in a dry and cool room. Molybdenum Disulfide should not be exposed to stress.

Packing & Shipping Molybdenum Disulfide MoS2:

The packaging depends on the amount of Molybdenum Disulfide MoS2 POWDER.

Molybdenum Disulfide MoS2 Poudre packing: 100g, 500g, 1kg/bag; 25kg/barrel.
