Metathesis of metal oxides provides a novel route to produce nanoscale oxide materials in an inexpensive and highly efficient way. This has been explained pictorially by M. A. Morris et al. on page 440 ff. using an oxide ‘tree’: Oxide anions are released from the ‘pool’ (alkali metal oxides serve as the oxide ion source) and are absorbed by the ‘root’ of the ‘tree’ and then transferred via the ‘trunk’ to form the ‘fruits’ (metal oxide nanoparticles) at the top of the ‘tree’. The different colors refer to the different condensation states of each oxide.
