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.

Color me impressed!
Color: Stainless Steel
Color me impressed! So far I really like this Typhur Sync oven. My first test was a frozen pizza. Unfortunately, it was overcooked. I really can't remember at this moment the exact temperature/time settings I used. (Probably used the box directions.) However, next time I'm going to just select the pizza setting on the oven and trust it. This is a convection oven, so I shouldn't have used the box directions. My next test was a big one. I cooked a 5.6 pound rib roast for Christmas. I selected “beef”, then “medium well”, then hit start. After the preheat was completed, I put the roast in the oven. Of course, before putting it in the oven I inserted the wireless temperature probe. I had taken the roast out of the fridge to let it get to room temperature an hour or so earlier. The probe said its internal temperature was 56 degrees, and the target temperature would be 140 degrees. I looked at other ovens as well, but selected this Typhur for its wireless probe and phone app that would track the oven progress and alert me when it was completed. The oven is downstairs, and this app would save me much stair work. It worked great! Love the little app. I checked the app from time to time for cooking progress, and it would tell me its current internal temperature and the target temperature. Also told me the time to completion. Amazing. It “dinged” my phone when the oven was done. I went downstairs and removed the roast. It looked fantastic. Of course while sitting on the counter top, the roast continued to cook internally while we were getting everything else set up on the dining table, thereby making it more like “well done” when we were finally ready to eat. After slicing it, the meat looked great. Not as pink as I wanted, but that was due to the “internal cooking” it did. I think next time, I'm selecting “medium”. Then it might be more like “medium well” when we're ready to eat. Also, did I mention that the cook time was just a little over 90 minutes? Couldn't believe how fast it cooked. My next test was cooking a pork tenderloin “medium well”. It took 33 minutes, and turned out great. Again, I'm very happy with this purchase. Back story... Years ago we remodeled our kitchen in a previous house, and not wanting to discard a perfectly good wall oven, I built a box for it and kept the oven in our garage to act as our second oven. Well, after 26 years it finally started failing. (Couldn't blame it for all the hot summer and cold winter cycles it went through.) Repair cost would be unreasonably high, even if the parts were available. Looking to replace it would cost anywhere between $450 (for a “no name” oven) and $1000 or more (for a “known brand” oven). I then saw these counter top ovens. After some study, I gambled and selected this Typhur Sync for $230 (also a “no name” brand to me at the time). Glad I did.

Good little oven
Color: Stainless Steel
Delivery was prompt. Wasn’t sure what to expect on the oven but the controls were fairly intuitive and have used several of the settings. Performs well on everything that we’ve used it for. The instructions are basic but adequate to get you cooking. The size was a little larger than anticipated, it is deeper and takes up more counterspace but you can cook a chicken in it! Looks great sitting on the counter. Not too industrial and the buttons and knobs make changing settings easy.

We love it!
Color: Stainless Steel, Color: Stainless Steel
Simply said, it’s great! My wife absolutely loves this little oven. It has a bunch of options to choose from for cooking. You can use it as an air fryer, oven, you can cook perfect crispy wings, as well as a nice piece of steak with the included thermometer. Since it’s very little compared to the regular house stove, its much easier and quicker to clean it. It’s a must have for any home!

Best Toaster Oven Ever!
Color: Stainless Steel
I've had the oven about a week now and have used it numerous times. The air fried wings came out perfect. The oven baked chicken was perfectly cooked thanks to the probe and crisped up nicely. Toast is fast and just the right color each time. I give the oven high marks for the value and features. The oven's performance exceeds my expectations. The only reason I did not give this gem 5 stars is due to the oven door handle. When open, the door handle hits the counter top preventing it from opening fully. When the oven is hot, pulling something out is an issue due to the door not opening fully. Otherwise, I highly recommend this oven.

Great Product and Great Customer Service
Color: Stainless Steel
This little countertop oven checks all of the boxes for me. First, even at its highest tempeture for baking bread at 450 the outside of the unit is warm to the touch but will not burn your hand. It has all of the settings one would want for an oven to do icluding, reheat, PROOF (for bread) broil, stay warm etc. I love it and the best of all of this was my experience with their customer service. I started having an electrical glich with the unit soon after I bought it and reported the problem to the company. Well, then it stopped having that problem but intermittently did. The light would come on by itself and sometimes I could not get the oven to turn on. So, this ensued off and on for several months until I decided to once again contact customer service to report my problem. They took my information and then informed me that they would be happy to replace the unit. All I needed to do was send my unit back after receiving the replacement. Which they did and I did and VOILA, problem solved just like that. No rigamarole, no hassle just excellent customer service.
