- Abstract
- beta-(Bi1-xSbx)(8)Pb5O17 has been shown to have very high oxygen-ion conductivity at temperatures as low as 600 degrees C; 1 s/cm has been reported in the literature. This paper describes how the material can be characterised using high temperature Raman spectroscopy. The effect of increasing x allows for a broadening of the peaks in the Raman spectra and a shift towards lower wavenumber. This can be explained in terms of the Sb atom deforming the room temperature tetragonal beta-structure and an incipient phase change in the high temperature beta-phase. This paper also describes the effect of low oxygen partial pressure on the sample. In general, as x increases, the width of the ionic domain, and hence the low P-O2 stability, increases down to approximately P-O2 = 10(-13) atmospheres. Below this dopant concentration, the stability again reduces.
