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.

They know the word "treatball"
My dogs love these treat balls. I give them one after each meal as a "dessert". I think it helps clean their teeth also, and it keeps them busy for a while.

Highly Recommend!!!
I bought a second set of these toys for my puppy who is a Chorkie because he LOVES them! They're super durable, very bouncy, extremely light weight, soft and flexible. They're the same size as a golf ball so they're perfect for small dogs. I would highly recommend these especially if you have a puppy who likes to chew and play fetch.

Perfect size and very durable! Flexible but sturdy.
Perfect for my Frenchton puppy. Easy to pick up in her mouth and they are flexible but sturdy. Unfortunately lost all three already, lol, so guess I’ll be buying more. 🤦‍♀️

More like a cat toy size ball. Still a good toy.
I should have paid more attention to the size as they are slightly bigger than golf balls. The ones I was looking for are identical but about the size of a grapefruit. My dachshund has one and it is her favorite ball toy. That's on me though. These are more of a cat toy size ball. These do look like they are the same material as my pups larger one which is durable and fun for her to throw and bounce. The holes make it easy for the pups to grab and run quickly or catch in mid-air. I'm not sure how other small dogs would do but these are too small to play tug-of-war with my little girl and she is definitely not as interested in them as she is with her bigger one. I think we will donate these to animal control since I am sure they have some small dogs or cats that would appreciate these more than our picky girl lol. Still a great toy but just not the size she likes.
