Abstract Existing hugoniot calculations of inorganic chemical reactions in powder mixtures are found to contain errors and ambiguities. Most of the problems were caused by improper identification of the thermodynamic reference state. The derivations have been revised using two different integration paths: i) constant volume, and ii) constant pressure. Sample calculations with a Ni-Al system show that the two schemes yield close results. The constant pressure scheme presents the possibility of self-sustained chemical reactions (detonations) occurring in condensed phase. An example of such a detonation in the Ni-Al system is numerically demonstrated with hydrocode calculations.
