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.

Interesting Concept, But Redundant If You Already Use BHA
If you have seen this Glow Rice Exfoliant Ampoule Duo on Instagram or TikTok, you already know the marketing pitch: a gentle, soft peel that physically cleans out pores on your face and body. After testing it, I can confirm that it actually does clean pores, but the mechanism is nothing magical. It relies on the friction of massaging the serum into your skin to clump up and manually extract dead skin and debris. It is a satisfying and interesting process to watch, but it isn't groundbreaking.The biggest drawback is its redundancy if you already have a solid skincare routine. I noticed that when I use this product after my usual BHA (Beta Hydroxy Acid) exfoliant, it becomes completely ineffective. Because the chemical exfoliant already cleans deep inside the pores and dissolves dead skin cells, this manual friction gel finds nothing left to grab onto. It is a decent, gentle physical exfoliant that does the job, but if you already use a chemical exfoliant like BHA, you can safely skip this social media trend.

Not as good as the real thing
I was really hoping to get a less expensive alternative to Dr Melaxin’s version. This just isn’t cutting it - it totally is not as effective, so I’m tossing this and going back. This one just doesn’t pill up as effectively.

Not as effective as original Dr. M
I bought this after reading several reviews that it is as effective as the original Dr. M. Having used both I can assert this product is NOT nearly as effective. I still had some of the original Dr. M. and did a half and half comparison and it was immediately clear. This exfoliate "pills" like the original but not nearly to the degree and when washed away the half I used the leftover Dr. M. was clean of dead skin and showed clear pores. The other half? Not so much. I'll be going back to the original.
