Inorganic Materials Aims and scope

Abstract

Lithium orthoberyllate, Li6BeO4 , was shown to have a pseudocubic structure with a= 8.834 Å, b= 8.977 Å, and c= 9.125 Å. The Li6BeO4–Li5AlO4 system contains Li5AlO4- and Li6BeO4-based solid solutions in the ranges 0–30 and 70–100 mol % Li6BeO4 , respectively. The highest electrical conductivity in the Li6BeO4–Li5AlO4 system is attained at 70 mol % Li5AlO4 (2.2 × 10–3 S/cm at 550°C). The electronic contribution is no greater than 0.1%.
