Abstract
A comparative analysis of the combustion profiles of SCS of lithium aluminate from a solution of aluminum nitrate and lithium nitrate or carbonate with glycine, leucine, and urea was performed. The influence of the starting solution composition on the maximum combustion temperature and combustion profile was considered. It was found that maximum combustion temperature, 771°C, is observed in case of synthesis of nitrate solution with glycine and urea (1 : 3). The appearance of ballast lithium aminoacetate during syntheses of aluminum nitrate with lithium carbonate and glycine was shown to reduce the maximum combustion temperature by almost 100°C. Replacing lithium nitrate with lithium carbonate decreased the temperature at which γ-LiAlO2 started to form and made it possible to obtain monophasic α-LiAlO2 after heat treatment at 500–550°C.
期刊介绍：
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
