| Popis: | By a variety of techniques including X-ray powder diffraction, quasielastic neutron scattering, and AC impedance, we have probed the effect of mechanical milling on the phase behaviors of the different lithium and sodium closo-borate salt compounds containing B 12 H 12 2 - , B 10 H 10 2 - , and C B 11 H 12 - anions. We have found that the crystallite-size reduction and disordering effects of such milling enables the room-T stabilization of their high-T-like superionic-conducting phases. This demonstrates a viable strategy for better exploiting the impressive cation mobilities that are typically restricted to somewhat higher temperatures for this class of compounds. |
