Abstract

<p>Lithium aluminate (LiAlO2) was produced by the following way. The metallic aluminum was dissolved in nitric acid solution using direct current power supply unit. Lithium carbonate was added in the above solution and then stirred with ammonia to be gel. The gel was calcined at 773–1473 K for 3.6 ks. X-ray diffraction analysis showed that the powders which obtained by calcining at temperatures of more than 1273 K were identified as γ-LiAlO2.The preparation of LiAlO2 above was considered from electrochemical points.</p>
