Abstract
Explored was the phenomenology of calciothermic reduction in model green mixtures containing metal oxides with strong (TiO2) and weak (MoO3) Me–O bonds. In case of high affinity metal (Ti), the process occurs in two stages: (1) combustion reaction of Ca with N2 yielding calcium nitride and (2) calciothermic reduction of TiO2 to give TiN. In case of low affinity metal (Mo), the above reactions proceed in parallel, without noticeable time delay.
