Micro-porous propellants containing titanium powder were obtained by supercritical CO 2 (SC CO 2 ) foaming technique. The morphologies of the micro-porous propellants were characterized by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) measurement. The burning rate, the impetus, and the heat of explosion of the micro-porous propellants were measured by the closed vessel test and the calorimetric bomb test. The results show that the porosity increased with in-creasing titanium powder content; compared with Benite, the burning rate was substantially improved, and the maximum values of the impetus and the isochoric heat of explosion increased by 51.4 % and 6.5 %, respectively. The Ticontaining micro-porous propellants with rapid burning rate and better energetic properties described in this paper may have the potential to replace Benite as igniter material in a flame igniter of a gun propellant charge.
