Abstract The work on the thermodynamics of aluminum nitrate nonahydrate decomposition has led to two manuscripts. The first, 'On the partial dehydration of aluminum nitrate nonahydrate to form the hexahydrate,' suggests mechanistic interpretations for the first two steps in the thermal decomposition process. The second, 'A computational equilibrium investigation of the thermal decomposition of aluminum nonahydrate,' covers the work on the thermal decomposition to diaspore and alumina. A discussion is given on the condition of kinetic control of the decomposition reactions of nitrogen in the +5 valence state (HNO3 vapor and N2O5) to uneconomical and undesirable gaseous nitrogen. One of the conclusions of the computations is that diaspore is the stable solid product below 200C and alumina above this temperature.
