FIELD: weapons and ammunition. ^ SUBSTANCE: proposed pyrotechnic particles include at least one oxidising component chosen from ammonium, potassium, sodium, barium, strontium nitrates, the main copper nitrate, ammonium, potassium and sodium perchlorates, and their mixtures, at least one reducing component chosen from nitroguanidine, guanidine nitrate and their mixtures and is not included in binding agent; at that, particles essentially have the shape of cylindrical blocks with thickness of more than 5 mm, with equivalent diameter equal to 10 mm or more, and with porosity in the range of 1% to 8%, including boundary values. Particles can be obtained in compliance with the proposed method. ^ EFFECT: proposed particles have low combustion rate, low working pressure, low dependence of combustion rate on working particle temperature in order to provide good ballistic properties at extreme temperatures; particles are not corrosive in relation to generator and have mechanical characteristics required to maintain the vibration in automobiles or aircrafts. ^ 14 cl, 3 dwg, 3 ex |
