Abstract

The reaction of crystalline lithium-stabilized Na-β”-Alumina with zirconium(IV) chloride at 400°C for 303h has caused sodium ions to exchange with zirconium ions. An X-ray crystal diffraction study of both the parent lithium stabilized Na-β”-alumina (1) and the partially zirconium exchanged product (2) have been made at 147 K. Crystal data for 1: rhombohedral, R 3 m, a = 5.6037 (3), c = 33.6210 (86) Å, V = 914.31 (24) Å3. Crystal data for 2: rhombohedral, R 3 m, a = 5.5994 (5), c = 33.7711 (51) Å, V = 916.96 (16) Å3. Zirconiums in 2 reside, predominately, in the Beevers-Ross type site.
