Product Overview

WO2.9, also known as blue tungsten oxide or blue tungsten, is a compound containing a mixed valence state of tungsten (VI) and tungsten (V). The chemical formula of WO2.9 indicates that the atomic ratio of tungsten (W) to oxygen (O) is about 2:9, but in fact it represents a mixed oxide containing different valent states of tungsten. This compound is formed by the combination of tungsten with oxygen in two valence states, W+6 and W+5, so its chemical formula can also be considered as an average composition used to describe its overall chemical properties. With its high chemical activity, WO2.9 can participate in various chemical reactions. Its reduction and oxidation properties are relatively weak, but the specific performance depends on the reaction conditions and the nature of the reactants. Moreover, WO2.9 also has good photochromic and electrochromic effects, and its color may change with different factors such as particle size or illumination.

Technical Parameter

Size:0-300nm

Purity:~99%

Appearance:Dark blue powder

Product Features

Catalytic activity and selectivity: WO2.9 has excellent catalytic activity and selectivity, and is suitable for various catalytic reactions such as hydrogenation, dehydrogenation, oxidation and reduction. In the fields of petrochemical industry, fine chemicals and environmental protection, WO2.9 as a catalyst can significantly improve the reaction efficiency and product quality stability: the stability of nanometer vanadium dioxide is relatively high, thanks to the special structure of its surface ion ripples, so that it can maintain good performance in a variety of environments.

Optical properties: WO2.9 has a unique blue luster, which can be used as an additive to materials such as optical glass, optical thin films and optical coatings to improve the optical properties and stability of these materials. It can also be used to prepare transparent heat insulation coatings and solar photosensitive films to meet the needs of optical materials in different fields.

Application Fields

Catalytic reaction: WO2.9 has excellent catalytic activity and selectivity, and can be used as a catalyst for hydrogenation, dehydrogenation, oxidation and reduction reactions to improve the reaction efficiency and product quality.

Lithium ion battery: WO2.9 can be used as a cathode material for lithium ion battery to improve the capacity and cycle performance of the battery.

Solar cells: WO2.9 can also be used as a photoelectric conversion material for solar cells to improve the conversion efficiency and stability of solar cells.

Optical field: WO2.9 has a unique blue luster and optical performance, which can be used as an additive for optical glass, optical film and optical coating materials to improve the optical performance and stability of materials.

Coating material: WO2.9 can be used as an additive for anticorrosion coating and wear resistance coating to improve the corrosion resistance and wear resistance of the coating.

A very comfortable shirt at a good price!
Size: Large, Color: Blue
Comes out very soft once washed! I ordered this shirt when I saw it and was curious how stiff the material was. I was expecting something a bit more coarse since it was western wear, but was pleasantly surprised to find that once washed it became very soft. The shirt is also very light and airy, and allows the breeze through to cool you off. I was also impressed with the quality of the shirt. All the stitching is tight and neat, and there were no threads hanging loose to catch on anything. As far as sizing goes, it was exactly what they recommended based on measurements, and it fits great. The cut of the shirt is pretty nice also with a bit of a taper, and it looks really good on (according to my wife, anyway). The shirt is versatile enough to wear out to dinner at the steakhouse, or to work in the yard. Bottom line: The shirt is comfortable, fits well, is good for work or going out, and a great deal for the money!

Looked amazing… but not built for broader shoulders
Size: Small, Color: Blue, Size: Small, Color: Blue
I got this for my husband because he’s fully leaning into his cowboy era lately (new boots, new attitude, the whole thing), and I thought this shirt would seal the deal. First impression—honestly impressed. The color is really nice and the embroidery detail looks great in person. It doesn’t feel cheap at all and definitely looks more high-end than expected. For reference, he’s about 5’6”, 140 lbs with an athletic build. The shirt almost worked—it fit well through the body and could be fully buttoned, but the shoulders were just too tight. As soon as he moved his arms, it felt restrictive, like the seams were being pushed to their limit. Which is a shame… because wow, he looked GOOD in this. And that’s coming from someone who doesn’t usually love this style. I’d say this shirt runs better for slimmer or narrower builds. If you’ve got broader shoulders or any upper body muscle, you may want to size up or skip this one. Overall, great quality and style, just not the right fit for an athletic frame.

A Western Shirt That Works as Hard as It Looks
Size: Medium, Color: Blue
A Western Shirt That Works as Hard as It Looks This men's western shirt strikes a really solid balance between style and everyday wearability. The cotton-polyester blend fabric keeps things soft and breathable without feeling too heavy, and the exquisite floral embroidery on the turn down collar adds a level of detail that makes it look far more elevated than a basic button down. Whether you're heading to a country concert, a western-themed party, or just pairing it with jeans and cowboy boots on a casual day out, it fits the moment without trying too hard. The versatility here is genuinely one of the stronger selling points. It works just as well at a rodeo or western-themed wedding as it does for everyday casual wear, and the timeless embroidered design means it won't feel dated after a season. Care is simple with machine or hand wash and hang to dry, so it's low maintenance for something that looks this put together. It also makes a thoughtful and practical gift for a husband, boyfriend, or father who appreciates a little western flair in their wardrobe. Just make sure to check the size chart carefully before ordering since sizing can vary with this style of shirt.

Well Made
Size: X-Large, Color: Navy Blue
When my husband put this shirt on, the women comment him on how he looks. I have to admit "He looks great in this attractive western shirt." The blue is a nice blue. He bought a black one, too and it is also very well made and nice looking. The sizing was perfect. It is wrinkle resistance, a great fabric thickness and comfortable. Definitely would buy him another if these ever wear out. It is a great value for the money.

Great Quality - Son loves it!
Size: Large, Color: Black
I ordered this beautiful Western shirt for my son for Christmas. He loves it so much he wears it once a week. The quality is excellent. The fabric is relatively thick, but not too thick - a nice, sturdy fabric. The embroidery is absolutely beautiful! It looks even better in person. The large fit him true to size, like all his other size large men's button up shirts. There are no loose threads or flaws in the stitching. It looks and feels expensive - well worth every penny of the $40 price. It has held up well in the wash. There has been no fading or shrinking. It is now March and it has been washed once a week since Christmas. (Please note - I don't put it in the dryer. I hang it to dry.) I highly recommend if you are looking for a fancy Western shirt.
