$10.95 $ 10. [38], MoS2 is employed as a cocatalyst for desulfurization in petrochemistry, for example, hydrodesulfurization.The effectiveness of the MoS2 catalysts is enhanced by doping with small amounts of cobalt or nickel. Depends on method of appliaction. Self-lubricating composite coatings for high-temperature applications consist of molybdenum disulfide and titanium nitride, using chemical vapor deposition. Its chemical formula is MoS2. The molar mass of the MoS2 is 160.07 g/mol. Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. It is insoluble in water and dilute acids. Please drop us a line and we will get back to you soon. Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. 4.9 out of 5 stars 9. MoS2 and related molybdenum sulfides are efficient catalysts for hydrogen evolution, including the electrolysis of water;[42][43] thus, are possibly useful to produce hydrogen for use in fuel cells. Bulk MoS2 is a diamagnetic, indirect bandgap semiconductor similar to silicon, with a bandgap of 1.23 eV. Molybdenum disulfide powders (MoS2 “Moly”) are used as lubricants or compounded into materials to provide inherent lubricity. EC Number 215-263-9. Phone: +61 8 6244 5397, A S Harrison & Co Pty Limited Prefer to buy all your stuff on Amazon? NCZ-NSC303/20 CAS No. [25], Bertolazzi and coworkers also characterized the failure modes of the suspended monolayer flakes. Each sulfur atom has pyramidal coordination and is bonded to three molybdenum atoms. Molybdenum Disulfide Powder is primarily used as a solid lubricant for its low friction properties and robustness. 75 Old Pittwater Road Molybdenum disulfide MoS 2 powder is generally used to prepare MoS 2 quantum dots solutions and nano-platelettes by liquid exfoliation assisted by sonication. [21], The wear resistance of MoS2 in lubricating applications can be increased by doping MoS2 with chromium. Usage From United States +C $11.51 shipping. In both of these structures, each molybdenum atom exists at the center of a trigonal prismatic coordination sphere and is covalently bonded to six sulfide ions. SECTION 16: OTHER INFORMATION HMIS Classification When added to plastics, MoS2 forms a composite with improved strength as well as reduced friction. [31] With butyl lithium, the product is LiMoS2. 2D MoS2 can be produced by exfoliating bulk crystals to produce single-layer to few-layer flakes either through a dry, micromechanical process or through solution processing. The strain at failure ranges from 6 to 11%. [10], A third, metastable crystalline phase known as 1T-MoS2 was discovered by intercalating 2H-MoS2 with alkali metals. Furthermore, different grades exhibit different physical or chemical properties. Interlayer sliding dissipates energy when a shear stress is applied to the material. Nano powder can be used as lubricants and for nano composites. Molybdenum Diselenide (MoSe 2) structure Applications. High-purity MoS 2 powder can also be used in CV deposition to prepare high quality mono-layer films. [20] Direct methods of measuring the shear strength indicate that the value is closer to 25.3 MPa. [7] Molybdenite ore is processed by flotation to give relatively pure MoS2. [16] Molecular dynamic simulations found the in-plane yield strength of MoS2 to be 229 GPa, which matches the experimental results within error. MoS2 has a hexagonal crystalline structure similar to graphite, WS2 and hBN lubricants. MicroLubrol 1/2 oz (0.5 oz, 14 grams) MOLYBDENUM DISULFIDE Moly MoS2 Powder SUPER FINE 1-2 micron BEST LUBE GRADE. Manufacturer of molybdenum disulfide powder used as lubricant for electric contacts in relays & switches. Sliding friction tests of MoS2 using a pin on disc tester at low loads (0.1–2 N) give friction coefficient values of <0.1.[34][35]. Obtained via the CVT method, MoSe 2 powder with purities of over 99.995% have been achieved. Rockingham, WA 6168 Australia In biosensing, the physical gate is removed and the binding between embedded receptor molecules and the charged target biomolecules to which they are exposed modulates the current. [54], MoS2 has been investigated as a component of flexible circuits. Specifications include temperatures ranging from minus 375 degrees F to plus 750 degrees F & particle sizes ranging from less than 1 micron to 100 microns. [55][56], In 2017 a 115-transistor, 1-bit microprocessor implementation using two-dimensional MoS2. Its chemical formula is MoS 2. Molybdenum disulfide is stable in air and attacked only by aggressive reagents. Compared to Graphite, another common dry lubricant, Molybdenum Disulfide has a lower coefficient of static friction, better overall lubricating qualities, and will not burn off due its high temperature resistance. MoS2 in particle sizes in the range of 1–100 µm is a common dry lubricant. All forms of MoS2 have a layered structure, in which a plane of molybdenum atoms is sandwiched by planes of sulfide ions. 6E Jack Conway Avenue The 1T-phase can be stabilized through doping with electron donors like rhenium,[12] or converted back to the 2H-phase by microwave radiation. Examples of applications of MoS2-based lubricants include two-stroke engines (such as motorcycle engines), bicycle coaster brakes, automotive CV and universal joints, ski waxes[36] and bullets. [16][24] The yield strength of monolayer flakes was 270 GPa,[24] while the thicker flakes were also stiffer, with a yield strength of 330 GPa. Runaway Bike PTFE Powder! [37], Other layered inorganic materials that exhibit lubricating properties (collectively known as solid lubricants (or dry lubricants)) includes graphite, which requires volatile additives and hexagonal boron nitride. Molybdenum Disulfide Powder Product Name: Molybdenum Disulfide Powder Product Name Molybdenum Disulfide Powder Catalog No. Molybdenum disulfide (CAS 1317-33-5) California Prop. The lubricating properties of Moly are a result of its planar structure … Molybdenum disulfide [molybdenum (IV) sulfide, MoS 2] is an inorganic compound that exists in nature in the mineral molybdenite. Its appearance is quite similar to graphite. Molybdenum Disulfide is also a common fortifying compound for high temperature and pressure lubricants, including dry films, oil dispersions, greases, and pastes. [58], MoS2 also possesses mechanical strength, electrical conductivity, and can emit light, opening possible applications such as photodetectors. Molybdenum powder is produced by a technique similar to that used for tungsten powder. US $42.90-$42.90 / Gram 5 Grams (Min. We can also provide nano molybdenum disulfide with purity 99.9%, particle size is 200nm. [41] The catalyst can also can effect hydrogenolysis of organosulfur compounds, aldehydes, ketones, phenols and carboxylic acids to their respective alkanes. While bulk MoS2 in the 2H-phase is known to be an indirect-band gap semiconductor, monolayer MoS2 has a direct band gap. Nanoscopic bending tests using AFM cantilever tips were performed on micromechanically exfoliated MoS2 flakes that were deposited on a holey substrate. Microindentation experiments on nanopillars of Cr-doped MoS2 found that the yield strength increased from an average of 821 MPa for pure MoS2 (0 at. The sensitivity of a graphene field-effect transistor (FET) biosensor is fundamentally restricted by the zero band gap of graphene, which results in increased leakage and reduced sensitivity. [33] Few alternatives exist that confer high lubricity and stability at up to 350 °C in oxidizing environments. The most studied nanotubes are made of carbon, but inorganic nanotubes have also been synthesized, including boron nitride, silicon titanium oxide, tungsten disulfide, molybdenum disulfide, copper, and bismuth. [6] MoS2 is relatively unreactive.

C $14.02. [2], MoS2 is naturally found as either molybdenite, a crystalline mineral, or jordisite, a rare low temperature form of molybdenite. [40] It is derived from a common transition metal, rather than group 10 metal as are many alternatives, MoS2 is chosen when catalyst price or resistance to sulfur poisoning are of primary concern. 65 Components This product does not contain any chemicals known to State of California to cause cancer, birth defects, or any other reproductive harm. Molybdenum Disulfide Powder Features Molybdenum disulfide is an important solid lubricant that is particularly suitable for high temperature and high-pressure applications. Molybdenum Disulfide is dry/solid lubricant powder, also known as the molybdenite (principal ore from which molybdenum metal is extracted), and has the chemical formula MoS 2. In digital electronics, transistors control current flow throughout an integrated circuit and allow for amplification and switching. Brookvale, NSW 2100 Depending on the conditions that are used in the grinding process, there are several different grades of this material.
