WS2 powder 3.8umProduct Name Name: WS2 powder 3. 8um Product Overview Tungsten disulfide (WS2) is a type of transition metal sulfide (TMDC) with a graphene like layered structure, where the layers are stacked together by weak van der Waals forces. Single layer WS2 is composed of three layers of atoms, with the atomic planes of W and S arranged in a hexagonal array. The W atoms are sandwiched between the two layers of S atoms, forming an S W S atomic layer structure

Product Overview

Tungsten disulfide (WS2) is a type of transition metal sulfide (TMDC) with a graphene like layered structure, where the layers are stacked together by weak van der Waals forces. Single layer WS2 is composed of three layers of atoms, with the atomic planes of W and S arranged in a hexagonal array. The W atoms are sandwiched between the two layers of S atoms, forming an S-W-S atomic layer structure with a "sandwich" structure. Multi layer or block WS2 is composed of single layers stacked together. Depending on the stacking method of the single layers, WS2 has three crystal structures: 1T, 2H, and 3R.

The synthesis methods of WS2 are mainly divided into two categories: "top-down" stripping method and "bottom-up" method. The "top-down" exfoliation method includes micro mechanical exfoliation, liquid-phase exfoliation, and lithium-ion intercalation, mainly using physical means to exfoliate the bulk WS2 into a single-layer or few layer layered structure. The "bottom-up" method includes chemical vapor deposition, hydrothermal method, and high-temperature thermal decomposition method, mainly using chemical means to grow atoms and molecules into nanoscale thin films and granular WS2 under certain environmental conditions.

Product Features

Layered structure: composed of a layered structure similar to graphite, with weak bonding between layers.

Good lubrication performance: With a low coefficient of friction, it performs well in the lubrication field and can effectively reduce wear between mechanical components.

Excellent electrical performance: It is a semiconductor material with certain conductivity and potential applications in electronic devices.

Good stability: It is not prone to chemical reactions with other substances in the environment and can maintain its structure and properties at high temperatures.

Application Fields

Lubricant: WS ¡ãCis a solid lubricant widely used in equipment for high temperature, high pressure, high speed, high load, and transportation in chemically active media.

Petroleum catalyst: WS ¡ãCcan be effectively used as a catalyst for hydrogenation, desulfurization, polymerization, reforming, hydration, dehydration, and hydroxylation processes due to its excellent cracking performance, high catalytic activity, and long service life.

Energy storage electrode material: WS ¡ãCis a layered material with good thermochemical stability, lithium storage performance, and fast electron transfer rate, which can effectively improve the energy density and structural stability of electrode materials.

Additives for high-performance lubricants: Adding an appropriate amount of WS ¡ãCnanoparticles to the lubricant can greatly improve its lubrication performance, reduce friction coefficient, and increase oil film strength.

Good quality - not very useful
Good quality utility pouch, downside is no recent phones will fit in this pouch as shown and the strap on the back is useless. Would've returned it but liked that it is waterproof and can hold thin items. Not the best value for the money if you wanted to protect a phone. Zipper is very sturdy. Too thin to be functional.

Very nice for the price!!!
Color: Black, Style: AEQ110W-1AV
Very, very Nice inexpensive watch!! Kinda tough to set it up but when done its well worth it. The icons glow so no light. The watch is a good smaller on my wrist than I expected but its functional not style Ineeded. Still a verry good watch, no questions asked!!

Well built under $50 watch.
I got this Casio as my first Casio as I've worn watches since I was a teenager, using non brand sport watches and eventually graduating to fancy Japanese watches. Now I found myself not wanting to use those to put on wear on them because they are automatic and require some maintenance, so I figured it was time I got my first Casio. I was skeptical at first because I knew I wanted a Casio but the designs were all, dare I say generic (Or so I thought) so I ultimately wanted a G shock but, for the price and intended purpose I found this watch that just checked the boxes in design and "10-Year" battery. When I got it in the mail I was stocked, I hadn't felt a resin watch in years and set up was straight forward. Now after weeks of use I've found that through a bunch of me smacking it and hand washes, it still looks new, fortifying my satisfaction in buying this. Can recommend.
