导出了描述结晶生长过程的3个热动力学方程和这些动力学方程的参数与常数间的2个关系式。用Calvet微热量计测定了RDX和HMX从二甲基亚砜、环已酮和硝酸中的稀释/结晶总放热量和产热速率。用导出的方程和关系式处理了RDX和HMX的放热稀释/结晶生长过程的动力学数据。结果表明,RDX和HMX的放热稀释/结晶过程服从Burton-Cabrera-Frank位错理论。
Three thermodynamic equations describing the crystal growth process and two relations between the parameters and constants of these kinetic equations are derived. The total heat of decay / crystallization and the rate of heat production of RDX and HMX from DMSO, cyclohexanone and nitric acid were determined using a Calvet microcalorimeter. The kinetic data for the exothermic dilution / crystallization of RDX and HMX were processed using the derived equations and relationships. The results show that the exothermic dilution / crystallization of RDX and HMX obeys the Burton-Cabrera-Frank dislocation theory.
