%0 Journal Article %T Synthesis and Properties of Laβ-Al_2O_3 %J 材料科学技术学报 %D 1997 %I %X Laβ-Al2O3 solid electrolytes were synthesized directly and their conductivities were measured in terms of ac impedance spectroscopy.The magnitude of conductivities is 10-6 to 10-2 S·cm-1.Based on these data, the dependence of the conductivity of Laβ-Al2O3 upon the temperature and the dopant concentration in the electrolytes was studied, and the activation energy for conduction was calculated, which is 0.89 eV to 1.02 eV from 450℃ to 1000℃. The ion transference numbers were also determined. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=84529CA2B2E519AC&jid=324DC3CAB22330DB19158AE0A9B7BFA5&aid=3355C045C586EA91&yid=5370399DC954B911&vid=FC0714F8D2EB605D&iid=0B39A22176CE99FB&sid=0B4F496D54044D86&eid=1B97AE5098AEB49C&journal_id=1005-0302&journal_name=材料科学技术学报&referenced_num=0&reference_num=0
