Aqueous solutions of Al(NO3)3.9H2O and LiNO3 were used as precursors, and NaOH was used as precipitant agent. After freeze-drying, the samples were calcined at several temperatures for characterization. The lyophilization process allowed the preparation of γ-LiAlO2 phase at 750 °C, which remained stable until temperatures about 1150 ºC, without the formation of other undesired phases as LiAl5O8. }, keywords = {&gamma,LiAlO2,coprecipitation,freeze,drying,TEM}, url = {https://aml.iaamonline.org/article_14832.html}, eprint = {https://aml.iaamonline.org/article_14832_d08aebf13a444c467e0d373552fd68ab.pdf} }
