Abstract
Official abstract text for this publication.
The present invention relates to a process for preparing an ammonium vanadium phosphate of formula (NH 4 )(VO 2 )(HPO 4 ). It also relates to a process for preparing a vanadium orthophosphate VPO 4 .
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for preparing a phosphate of formula (NH 4 )(VO 2 )(HPO 4 ), the process consisting of stirring a mixture of V 2 O 5 and of NH 4 H 2 PO 4 in the solid state and adding water in an initial proportion of between 0.1% and 200.0%, this proportion being calculated relative to the whole of the two reactants V 2 O 5 and NH 4 H 2 PO 4 , wherein V 2 O 5 and NH 4 H 2 PO 4 are powders that comprise particles having a diameter d 50 of at most 100 μm…
