Abstract
The work on the thermodynamics of aluminum nitrate nonahydrate decomposition has lead to two papers. The first suggests mechanistic interpretation for the first two steps in the thermal decomposition process. The second covers the work on the thermal decomposition to diaspore and alumina. A discussion is given on the condition of kinetic control of the decomposition reaction of nitrogen in the +5 valence state to uneconomical and undesirable gaseous nitrogen. One of the conclusions of the computations is that diaspore is the stable solid product below 200 deg C and alumina is the stable solid product above 200 deg C.
