Abstract:

The far infrared and laser Raman spectra of cation-substituted materials based on sodium beta-alumina containing K, Rb, Cs, Ag, Tl, Ca2, Sr2, Pb2, Mn2, Fe2, Co2, and Ni2 have been obtained. The materials were prepared by ion-exchanging sodium-beta-alumina with pure or mixed molten salts of these ions according to the Yao-Kummer and Harata methods. The spectra were obtained at various degrees of cation substitution so that the growth at disappearance of spectral bands could be used to assign them to vibrations of the ions to the different types of sites they occupy. Through the use of this technique, cation vibrations at mid-oxygen mO, Beevers-Ross BR, and anti-Beevers-Ross aBR sites have been identified. Author
