百科释义

In fireworks, a burst charge is an energetic pyrotechnic mixture placed in a shell which is ignited when the shell reaches the desired height in order to pass fire to and spread the stars. Burst charge compositions are usually coated onto rice hulls or other low-density fillers, which increases the rate of combustion.
