Abstract—Using thermal analysis, we have studied the decomposition of self-propagating high-temperature synthesis precursors consisting of scandium nitrate (oxidant) and three types of fuel: scandium acetate, scandium acetylacetonate, and glycine. Comparison of thermogravimetry and differential scanning calorimetry data for starting reagents and reaction mixtures indicates that the initiation of chemical reactions underlying SHS is associated with the thermal destruction of the oxidant. Analysis of the obtained data in terms of a modified Sestak–Berggren method has been used to assess kinetic characteristics of interaction between reactants in the reaction systems studied.
