Ball milling-induced pyrochlore-to-tungsten bronze phase ...

2011-1-1  The hexagonal phase produced by high-energy ball milling of RbNbWO 6 transforms back to the pyrochlore structure upon heating to 773 K in air. A similar phase was obtained by ball milling the mixture RbNbWO 6 + WO 3, but, in this case, the stoichiometric hexagonal tungsten bronze compound thus obtained remained stable up to 1273 K.
