The decomposition reaction of lithium amide studied by anelastic spectroscopy and thermogravimetry

The high temperature decomposition transformation of lithium amide into imide has been studied by anelastic spectroscopy and thermogravimetry. At the amide-to-imide phase transformation a huge elastic modulus increase takes place, whose change increases with the evolution of the decomposition. The modulus variation has been used to monitor the time and temperature progression of the reaction, and indications have been obtained that the reaction rates are faster than those usually reported. Moreover, formation of different phases is also detected at extremely low concentrations.
