Product Overview

 

Vanadium dioxide is a deep blue crystal powder with a monoclinic crystal structure, which can be industrially produced by gas reduction of ammonium vanadate or vanadium pentoxide (V2O5). VO2 is a amphoteric compound that is slightly soluble in water and equally soluble in acidic or alkaline solutions; When dissolved in acidic solution, it generates divalent vanadium oxide ions (VO2+), which appear light blue; When dissolved in alkaline solution, it generates vanadate salts M2V4O9 or M2V2O5. VO2 is in a metastable state, where V4+is easily oxidized to V5+, exhibiting relatively weak antioxidant capacity. VO2 is a polycrystalline metal oxide with five main structures: VO2 (M), VO2 (R), VO2 (A), VO2 (B), and VO2 (C).

Product Features

 

Phase transition characteristics: Vanadium dioxide nanoparticles can achieve a reversible transition from insulating phase to metallic phase at a specific temperature (68 ¡ãC, accompanied by significant changes in conductivity and optical properties.

High specific surface area: Nanoscale vanadium dioxide particles have a larger specific surface area, which is beneficial for increasing their surface active sites and catalytic efficiency.

Strong chemical inertness: The surface of nano vanadium dioxide has a large number of active sites, but due to the small amount of surface vacancies, its chemical inertness is very strong, and its adsorption performance for various harmful gases is excellent.

Good stability: Nano vanadium dioxide has relatively high stability, thanks to its special structure of surface ion ripples, which enables it to maintain good performance in various environments.

High catalytic activity: Nanoscale vanadium dioxide particles have significantly improved catalytic activity due to their high specific surface area, making them suitable for various catalytic reactions.


Application Fields

 

Smart windows: By utilizing the phase transition properties of vanadium dioxide nanoparticles, smart windows can be prepared. At high temperatures, windows appear metallic, blocking heat transfer; At low temperatures, windows become transparent, allowing light to pass through. This smart window can automatically adjust its transparency according to changes in ambient temperature, improving energy efficiency.

Photoelectric switch: Based on the phase transition characteristics of vanadium dioxide nanoparticles, high-speed photoelectric switches can be prepared. By controlling the temperature, switching between different phase states can be achieved, thereby regulating the transmission of photoelectric signals. This type of photoelectric switch has important applications in fields such as information processing and data storage.

Sensors: Various sensors can be prepared by utilizing the significant changes in electrical and optical properties of vanadium dioxide nanoparticles during phase transition. For example, using changes in conductivity to sense physical parameters such as temperature, humidity, and pressure; Utilizing changes in optical properties for optical sensing and spectral analysis.

Catalyst: Nano vanadium dioxide is widely used as a catalyst for various catalytic reactions due to its high catalytic activity and strong chemical inertness. For example, it can be seen in reactions such as nitration, ethane dehydrogenation, methane oxidation, and hydrogenation of formic acid.

Heavy duty for sure
Color: Purple
Heavy duty toy. This ball has some weight to it! I have a smaller laber doodle that thinks she's a German Shepard so no toy is too big or heavy for her. She's been chewing on this for months but you'd never know it. The squeaker is even hard for me to activate with my hands. She hits it in the right spot every now and again and gets excited about it. Great if your not crazy about hearing a squeaker squeaking non stop!

All dog sizes can enjoy this ball!
Color: Orange
This is a terrific dog ball! Our Pittie can't tear it apart on day 2 which is unusual! Also, its big enough that he can't swallow it but not so huge that our mini Doodle can't enjoy it too! We have more than one of these to keep our pups busy!

Finally, a ball that made it!
Color: Blue, Color: Blue
I don’t know what is it with this ball, but it’s special. My dogs can absolutely tear up anything and this one seems like it can be chewed up but my dog loves it too much. He carries it all day, nibbles it and loves the squeaky sound of course. Finally found a winner!

Good size ball for my big boy
Color: Purple
My big boy loves this ball. He chews and chews and chews on it and it ain't made a dent in it. It's made a good quality rubber. It's got a squeaker in it. He hasn't managed to get it out which is not normal because normally he can get a squeaky out within 10 minutes. He goes through toys like I don't know what so it's being being a good. Really good ball. We've had it for about 2-3 months now and he hasn't been able to break into it and get squeaky out or even make a dent into it. That would tear up the the rubber
