METHOD OF OBTAINING NANONEEDLES OF SODIUM VANADIUM OXIDE BRONZE Russian patent published in 2015 - IPC C01G31/00 C01D13/00 B82B3/00 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: invention can be applied in the production of a cathode material for chemical current sources, as well as thermistors, resistors, devices for information recording and storing. The method of obtaining nanoneedles of sodium vanadium oxide bronze with the composition α'-NaV₂O₅ includes obtaining a reaction mixture, which contains sodium metavanadate hydrate NaVO₃·2H₂O, and addition of sodium hydroxide to the mixture until pH 7.5-9.5 is set. The reaction mixture is placed into the autoclave and hydrothermal processing, heating to 140-180°C and exposure at the said temperature for 24-48 hours are carried out. The reaction mixture additionally contains vanadium sulphate hydrate with the composition VOSO₄·3H₂O, taken in an equimolar quantity relative to sodium metavanadate hydrate. The obtained product is filtered, washed and dried.

EFFECT: invention makes it possible to exclude the application of harmful or toxic substances, included into the reaction mixture composition.
