Particle Scattering Studies on Foreign Ions in Superionic Conductors.

Abstract

The effects of foreign ions on the structures and properties of superionic conductors are being investigated. This paper reports Rutherford backscattering, nuclear reaction analysis, and channeling studies on NaBeta-alumina crystals doped with Mn by ion implantation and with Li and Mg from melts. Implantation disorders the NaBeta-alumina surface. On heating, the surface crystallizes, and Mn diffuses into Al sites. The melt-doped compositions are accounted for by Mg substitution in the spinel layer and by Li in the conduction plane. Particle scattering has been used to profile sodium and impurities in NaBeta-alumina ceramics and F disorder in Beta-PbF2.
