Abstract

The proposed two-step preparation route for rare earth polyborates, i.e. dehydration of boric acid in the presence of rare earth oxide at low temperature followed by careful annealing at 700 °C, led to, for the gadolinium case, a new gadolinium pentaborate (GdB₅O₉) that can not be prepared by conventional high-temperature reaction.
