摘要：

A new type of strontium beta -alumina was developed by a simple solid state reaction. Polycrystals of Sr beta -alumina with the chemical formula of SrMgAl//1//0O//1//7 were prepared and examined by ac conductivity. The values of ionic conductivity in the Sr beta -alumina were 5 to 3 orders of magnitude lower than those of polycrystalline Na beta -alumina between 773 and 1273 K. The ion exchange of Sr beta -alumina for sodium was also examined, and the values of conductivity for the partially ion-exchanged samples increased with the increase of the excess amount of Na** plus up to 0. 5-0. 6 in comparison with that of the ideal Na beta -alumina.
