To assess the reactivity of nanothermites, the mathematical model of ignition of a nanothermite tablet by a hot body or radiation flux is expanded to take into account the incomplete homogeneity of the mixture. An approximation expression is given for the ignition time depending on the conditions and degree of homogeneity. Keywords: nanothermite, degree of homogeneity, ignition, reactivity.
