Color: Brown-red.
General Comments: Room temperature form of vanadium pentoxide gel.
The room temperature gel is observed by X-rays in reflection geometry.
Only 00l reflections are observed because of the orientation of the platelets; hk0 reflections can be observed in transmission geometry, but there is a turbostratic disorder between the platelets which means that there are no hkl reflections.
Sample Preparation: The vanadium pentoxide is prepared by exchange of ''Na V O3'' through a cationic exchange resin from which results unstable ''H V O3'' species ''H V O3'' polycondensates giving rise at room temperature in a few hours to a deep red gel.
This gel dried at room temperature and room humidity on a glass substrate (dip coating).
This gives rises to the so called "xerogel".
