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.

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.

Works great as advertised
Style: Printer & Inks, Style: Printer & Inks
Working great so far! Enjoying starting doing sublimation work. A rookie a few weeks in and it's going well. Print quality is decent. Not having paper jam issues. Was easy to setup. I had to goto Epson and download a current print driver to get all the print properties and printer settings I needed. Was easy. After I installed the 2nd driver and saw it worked better, then I uninstalled the 1st epson driver. Helped allow for 8.5 x 14 page size and high quality. Just a few options needed that were not showing on the original print driver. Took me a few days to figure out what was going on. It helped with the quality of the prints after I got the better driver. So the end product is better also.

Got the printer a week ago and have printed something every day so far and the quality of the prints have been fantastic. Arrived and set up without any major issues, other than not being able to connect to my local wifi. Had to get an Ethernet cable to connect to it.

Great 🥰

The Epson F170 has been ideal for getting started with sublimation. It's easy to use, prints vibrant and defined colors, and has allowed me to personalize various projects with excellent results. As a beginner, it has given me a lot of confidence to learn and create without complications. I definitely recommend it for anyone starting out in sublimation.
