The equilibrium states of KNO3/C6H5NO3/NC composition were calculated in least free-energy principle. The feasibility of new igniting charge substituting for black powder were disscussed from decomposition process,sensitivity and combustion property. Compared with black powder,impact,friction and electrostatic sensitivities of KNO3/C6H5NO3/NC composition decreased obviously. Combustion heat and working capabilities were increased by about 57% and 40%,respectively. Its use in central tube ignition system show that the peak value of in-bore pressure wave is about -20 MPa,and the interior ballistic properties are improved evidently.
