Linear burning rates ( r ) and rates-of-pressure rise were measured for some guanidinium 1,5’-bis-1H-tetrazolate (G15B)/ammonium nitrate (AN)/additive mixtures in which the additive tested was one of : manganese dioxide MnO2, copper Cu, copper ( I) oxide Cu2O, copper ( II) oxide CuO, basic cupric nitrate (BCN), copper phthalocyanine (CuPc), activated carbon (AC), sodium nitrate (NaCl), chromium oxide (Cr2O3) or silicon oxide SiO2. Linear burning rate test results show that all the additives tested enhanced the ignition of the stoichiometric ratio G15B/AN mixture, which by itself did not burn even under N2 atmosphere at an initial gauge pressure of 10 MPa at 298 K, and that the mixture with AC or CuO additive was faster in r than the commercialized guanidine nitrate (GN)/strontium nitrate (SrN)/BCN mixture under the whole pressure range that was tested (0.1-10 MPa (initial gauge pressure)) while the mixture with Cu, Cu2O, BCN or NaCl additive was faster under average absolute pressure over 5 MPa. As for the rate-of-pressure-rise test, all mixtures with one of the additives burnt completely three times out of three tests and that the mixture with Cu, Cu2O, CuO or BCN additive was, although higher in the average temperature-rise, also higher in both the average pressure-rise and the average rate-of-pressure-rise, while the mixture with AC additive was higher in both the average pressure-rise and the average rate-of-pressure-rise and lower in the average temperature-rise.
