摘要：

Single crystals of Na+-beta-alumina have been exchanged by rare-earth ions (Pr3+, Nd3+, Ho3+) using molten lanthanide trichlorides. Chemical analysis revealed exchange rates up to 95% for the sodium ions. Powder X-ray photographs showed a decrease of the c lattice parameter of about 0.1 angstrom for nearly completely exchanged samples.
