Three thermokinetic equations describing the crystal growth proces sand two relationships between the pa-rameters and the constants of the kinetic equations are derived. The thermokinetic data ofcrystal growth processes of RDX and HMX are treated based on the derived equations and relationships. The results show that the exothermic dilution/crys-tallization processes of RDX and HMX are the first order reaction and accord with the dislocation theory·
