Web31 mrt. 2014 · Li containing β - alumina was prepared by an ion exchange procedure by heating the original Na β - alumina sample in molten LiCl at 700 °C for a total of 48 h. The ion exchange process was completed in two steps. At first, the Na β - alumina samples were kept in to the molten LiCl for 24 h at 700 °C. The samples were then washed and … WebThis paper presents measurements of ionic conductivity in single crystals of Li+ and mixed Li+/Na+ beta alumina. The crystals were prepared by ion exchange of Na+ beta alumina crystals in , , or with added. The measured room temperature conductivity of Li+ beta alumina, about , is higher than earlier values. The activation energy was found to be …
