Abstract

The present work is on the study of Na β-Al ₂O₃, a ceramic that belongs to a family of oxides exhibiting fast-ionic conductivity. Na β-Al₂O₃ has the best solid electrolyte properties. This material is appropriate for use in electronic devices. NaAl ₇O₁₁, NaAl₁₁O₁₇, and Na₂MgAl₁₀O₁₇ are well known three compounds in the system of Sodium beta-alumina ceramics. NaAl₇O₁₁, Na₂ MgAl₁₀O₁₇, and NaAl₁₁O₁₇ compounds were prepare by combustion method in a single step. Attempts to synthesize NaAl₁₁O₁₇ by combustion synthesis failed. Metal nitrates as oxidizer and urea as a fuel are the starting material for preparation of these compounds. The method used is combustion synthesis, which is feasible, low cost, and a time saving method. Among the three compounds used in this study, NaAl₇ O₁₁ and Na₂MgAl₁₀O₁₇ show better results. NaAl₁₁O₁₇ doped with rare earth ions like Cerium and Europium could be achieved.
