【Abstract】 Aim The different pyrotechnic effects of black powder were summarized and the composition selection was studied. Methods By means of measuring burning rate, explosion temperature and gas volume at the normal pressure, the triangular coordination was drawn, pyrotechnic effects in different areas were analyzed. Results The combustion characteristics and rule of pyrotechnic effects were found. Conclusion The different mixture ratios of three ingredients of the black powder can produce different pyrotechnic effects.更多还原
