The preparation of sub-micron spherical phloroglucinol-fe and its effects on thermal decomposition of hexanitrohexaazaisowurtzitane

Sub-micron spherical phloroglucinol-Fe is prepared by spray drying. The morphology, particle size and composition of products are characterized by using TG-DSC, SEM and FTIR. The effect of phloroglucinol-Fe on thermal decomposition and kinetic parameter of hexanitroheraazaisowurtyzitane (CL-20) is studied by means of DSC. The research results show that the products are spherical and diffusive. Particle size is in the range from 500 nm to 1 000 nm. The product can obviously promote the decomposition performance of CL-20 so that the first decomposition peak temperature is shifted 15.1℃ ahead. The activation energy of CL-20/ phloroglucinol-Fe is increased by 81.4 kJ/mol compared with CL-20.
