Abstract

Linear burning rates and rates-of-pressure-rise of some guanidine derivative compound/ammonium nitrate (AN)/copper (II) oxide (CuO) mixtures, where guanidine derivative compound was either guanidine nitrate (GN) or nitroguanidine (NQ), were measured. While GN/AN/CuO mixture with 5 wt% CuO has shown the maximum linear burning rate among GN/AN/CuO mixtures that were studied, and also close to that of GN/strontium nitrate (SrN)/ basic copper nitrate (BCN) mixture that is used commercially as gas generating agent for automobile airbag inflators, all NQ/AN/CuO mixtures that were studied has shown equivalent burning rates and also equivalent to that of GN/SrN/BCN mixture. As for the average rate-of-pressure-rise, GN/AN/CuO mixture with 5 wt% CuO has also shown the maximum value among all GN/AN/CuO mixtures that were studied and also close to that of GN/SrN/BCN mixture, while NQ/AN/CuO mixture with 10 wt% CuO has shown the maximum value among all NQ/AN/CuO mixtures that were studied, and also exceeding that of GN/SrN/BCN mixture.
