Cationic replacements in the arsenates NaCa 2 M 2 > > 2 (AsO 4 ) 3 (M 2 > > ‫؍‬ Mg, Ni, Co) have a strong influence on their garnetalluaudite polymorphism. The preferential formation of an alluaudite phase (at the expense of the garnet phase) is induced by the following cationic modifications: (i) T

The substitution in Na 3 Fe 2 (AsO 4 ) 3 of Na Ψ‰ by either Li Ψ‰ or Ca 2Ψ‰ and a vacancy, is able to stabilize an alluaudite structure at the expense of either the garnet or the rhombohedral structure of the parent compound. In the system (Na 1؊x Li x ) 3 Fe 2 (AsO 4 ) 3 , pure garnet phases are obtai
