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.

Received the package in good condition. This wire is a decent quality. I made a set of jumper cables with it and they work excellent.

bought twice to make custom UPS setup battery leads, not disappointed
Color: Black, Size: 25-Feet
bought this item(25ft 2awg) twice, the first time I did was to create some quick connect cables between my batteries and my distribution block to my 4kw invertor(24v 165a peak calculated load) I may have oversized due to knowing that the bigger you go the less you stress components and loose power to voltage drop these cables are a nice high-grade rubber jacket and the 30awg strands are ideal for maximum flexibility while remaining fairly easy to terminate this cable also includes a backer paper wrap that allows for easy stripping(of the rubber) without too much strand loss damage(from cutting too close to the core) overall, would buy again, like I did, if I need larger runs(say for feeding an RV solar AC distribution panel) I would buy this brand again, in the 100ft range or so THHN is not ideal for flex connections(strands are way too stiff) but a couple runs of welding cable like this inside something like "smurf tube" would be a perfect high-power temporary connection system, or just a way to isolate a large battery stack used for a solar setup in fact I may do that someday, set up a pallet of LiFePO4 batteries with a large quick connect, and just recharge the massive array(s) at a secondary location where solar is more ideal(or other renewables)

Custom wires for winch solenoid pack relocation.
Color: Black, Size: 25-Feet
Wire is nice. Flexible. Seems good. However the inner liner is not moisture blocking as I assumed from the pictures, it's paper.. still seems like a good price per foot.

Good, flexible (considering it's 2 GA) wire
Color: Black, Size: 20-Feet
Good, flexible (considering it's 2 GA) wire. Lugs soldered on well (using solder pot + flux). The only reason I didn't rate it 5 stars is because it's expensive. Made in USA was a +
