Lead citrate, decomposition

Decompositions of chemically dissimilar substances (including NiC204, PbCjO, KNj, (NH4)2Crj07) may exhibit similar kinetic behaviour, whereas the decompositions of similar reactants (e.g. oxides) may exhibit apparently unrelated rate characteristics [60]. Decomposition data for very different reactants may be described satisfactorily by the same rate expression, for example the Avrami-Erofeev equation, with n = 2, has been reported as representing the decompositions ofFeC204 [61], KMn04 [29], silver malonate [62], nickel squarate [18], lead citrate [63] and d - LiK tartrate [64] (no common constituents in these six reactants). 

Citrate method is probably the most widespread and the most effective route to create high-surface-area perovskites (Figure 18.4) [23]. Additionally, the decomposition of the amorphous citrate precursors leads to mixed oxides or solid solutions of high homogeneity. Although often considered as a sol-gel method, citrate is a specific route. The comparison of the two mild chemical...
