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 1185degC. 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 rises, 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 potassium hydroxide or sodium hydroxide, (the goal is to convert molybdenum trioxide into molybdate), the titanium iron reagent is then added in dropwise. This method is sensitive enough to detect trace amounts. The solution will not turn golden yellow if no molybdenum dioxide is generated. This is because molybdenum dioxide does not react well with either sodium or potassium hydroxide.
Molysulfide Can react with chloride when heated to form molybdenum penteachloride
2 MoS2+ 7 Cl2- 2 MoCl5+ 2 S2Cl2
LixMoS2 (interlayer compound), a compound formed by the reaction of molybdenum disulfide with alkyllithium, can be obtained under controlled conditions. 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 alloys and copper need to be greased, it's not impossible to add copper-corrosion inhibitors, as well as molybdenum diulfide lubricants.

How do you pronounce Molybdenum Disulfide MoS2 Poudre produced?
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 other impurities can be further refined 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. Therefore, it is recommended that you use the MoS2 based on cost.
Chemical synthesis
Synthetic method is able to prepare sulfides which are high in purity, have less impurities and small particles, as well as sulfides meeting different functional requirements. Synthetic methods have always been used to produce nano sulfides. There are several methods of preparing nano-MoS2, for example, the thermal decomposition of ammonium, the hydrogen sulfide, or sulfur reduction method. Other methods include high-energy milling, carbon nanotube confinement, hydrothermal method, physical method with chemical method combination, high energy ball milling, 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 obtained from molybdenum concentrate that has 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 service life of equipment by being suitable for high temperatures, high pressures, viscosities and high loads.
Molybdenum Disulfide is primarily used as a frictional agent to reduce friction and combustion loss at low temperatures. It also increases friction at higher temperatures. The friction material is easily volatilized.
Anti-friction. Disulfide particle size can reach 325-2500 Mesh, particle hardness can reach 1-1.5, and friction coefficient can be between 0.05 and 0.1. It can thus be used to make friction materials that take advantage of its anti-friction properties;
Molybdenum dioxide is a non-conductive material. Molybdenum, trisulfide or trioxide, as well as silicon carbide are all present. The shrinking molybdenum Trioxide particles heat up and expand when the temperature of the friction materials rises rapidly due to friction.
Antioxidant : Molybdenum Disulfide, obtained from a comprehensive chemistry purification, 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:
