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

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 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.

Cheap and good
Color: Black, Color: Black
I chose the color black and it gives a really nice look, especially with the multicolor led lights around the keys. It is very easy to clean and you can shut off the keyboard to prevent any mess with the iPad. The magnet is very nice and keeps the keyboard in place. The keyboard doesn’t easily slip or anything so it holds the iPad very well. Only bad thing is that over time the iPad begins to scrape off the pain and it leaves your keyboard with some white spots all over :/ but if looks isn’t something that you care about, this is the keyboard for you. Don’t use it for gaming because there is a delay in functionality when you press a key and then try to use the pad. Also, you have to press the keys a bit harder than the usual keyboard. But for the price? This is a great item! Definitely worth my money

Great quality and functional
Model: iPad 11th A16 2025/10th, Model: iPad 11th A16 2025/10th
Fantastic screen protector! Adheres flawlessly and is easy to install. Doesn’t interfere with screen functionality and doesn’t go cloudy or hazy with use. It fits perfectly on my iPad 11 and was an absolute bargain compared to other protectors that cost 3x as much and never stayed in place without bubbling. Color is crystal clear, you can’t tell it’s there and it is easy to clean too! I definitely recommend!

Superb screen protector
Model: iPad 11th A16 2025/10th
Order this product with next day delivery for my new iPhone and I’ve had it on there for about a week. It was super easy to put the screen on the phone. It comes with like a guy that looks almost like a cover so excellent no air bubbles underneath knock on wood. I have not dropped my phone yet so I can’t speak to. It’s protectiveness but it seems like it’s gonna do a great job. I would definitely purchase again reasonable price good quality.
