Molybdenum disulfide makes up the majority of molybdenite. Metallic luster black powder. Molten point 11.85°C, chemical formula MoS2, density 4.80g/cm3. (14). Purity:98.5 – 99% Particle sizes: 5mm, 1.5mm, 10mm Molybdenum Disulfide MoS2 Pulp: Molybdenum dioxide, an organic compound that is made up of molybdenum as well as sulfur. Molybdenum sulfide whose chemical formula refers to MoS2. Molly disulfide is similar to other mineral salts. However, it has a high melting-point but melts at low temperatures. It begins to dissolve at approximately 450oC. This compound can be classified as a dihalide of transition metals. Molly sulfide (the principal ore molybdenum) is a solid that’s silvery-black. MoS2 can be quite reactive. It does not react to oxygen or dilute acids. It is very similar in appearance to graphite. Due to its high friction and durability, molybdenum disulfide is widely used in dry lubricants. Bulk MOS2 is an indirect bandgap diamagnetic semiconductor that has the same bandgap as silicon. MOS2 is also a semi-conductor. The fact that it can be doped with an electrical field makes it and other semiconductor chalcogenides superconductors. MoS2 or related molybdenum-sulfides can act as catalysts to hydrogen evolution. The electronic and optical properties of MoS2 and the other transition metal dibalcogenides’ layered structures are different from that in bulk graphene. Bulk MoS2 exhibits an indirect bandgap value of 1.2eV while monolayers MoS2 display a direct electronic bandgap value of 1.8eV. Photodetectors and switchable transistors are supported. Zero band gap in graphene limits the sensitivity of graphene FET biosensors. It also results in greater leakage, and lower sensitivity. Digital electronics use transistors to control the flow of current in integrated circuits and enable amplification or switching. The physical gate in biosensing is taken out and the current flow is modulated by the binding between the embedded receptor molecules of the charged target biologicalmolecules. MoS2 is also strong in electrical conductivity and mechanical strength. Additionally, it can emit light. This opens the possibility of using MoS2 as a photodetectors. MoS2 is a component in photoelectrochemicals (e.g. Applications for photocatalytic hydrogen production (e.g.

How are Molybdenum Disulfide MoS2 Pulp made? MoS2 naturally occurs as molybdenite (a crystal mineral) and pyroxene, which is a rare low temperature form. To get relatively pure MoS2, the molybdenite can be processed using flotation. The major pollutant in the molybdenite is carbon. MoS2 can also produced through heat treatment of most molybdenum components with hydrogen sulfur or elemental sulfide. This can be done by using the metathesis reaction molybdenum pyloride.
Molybdenum Disulfide uses: Molybdenum disulfide, also known as dry lubricant, is used for, e.g. Greases, dispersions and friction materials are some of the lubricants that Molybdenum Disulfide can be used in. While molybdenum sulfur complexes can be used in suspension, these compounds are most commonly found in liquid lubricating oils in concentrations as low as a fraction of one percent. As an additive in greases, friction oils, plastic, rubber and nylon as well as coatings, MoS2 may be used. 1) It is used extensively in both the mechanical and automotive industries. 2) Lubricant to use with drill bits, cutters and other non-oil and high alloy steels; Lubricant additive for non-ferrous metals and film remover. (3) Preparation of oils and other additives for solid lubricant films and nylon filters. The catalyst used to de-sulfurize oil refineries is synthetic MoS2.
Molybdenum Disulfide MoS2 powder Storage Conditions: MoS2 powder performance and use will be affected by the presence of damp. Molybdenum Disulfide MoS2 Puffer powder should therefore be kept dry and in vacuum packaging. Molybdenum Disulfide powder must be kept away from stress.
