A chimie douce method has been used to prepare vanadates (V5+) of various elements, trivalent (Al, Cr, Fe, In, Y, Bi), divalent (Co, Ni), monovalent (Li, Tl), and a combination of nickel and lithium. By varying several parameters, especially the pH during the synthesis, several types of vanadates have been obtained ranging from orthovanadates (VO43–) to decavanadates (V10O286–). The pH conditions required to prepare the various vanadates fall nicely within the expectations of the previously reported cation charge-pH diagram.
