Li+ Conduction in the Beta Alumina Structure

摘要: Li+ is one of several monovalent cations known to completely replace Na+ in beta alumina. The conditions under which ion exchange brought about determine whether the product pure alumina or containing both and Li+. Many investigators have believed that this process leads cracking polycrystalline and, therefore, not a satisfactory route for preparation. It also has been reported single crystal ionic conductivity only 1.6 x 10−4 (ohm cm)−1 at 25°C, 90 times less than alumina.1,2 work discussed paper indicates neither these points true.
