    摘要: A novel pyrotechnic delay composition for use in metal delay fuse cartridges, including as its primary constituent Si—Al—Fe3O4 prepared from powdered form. The delay composition yields a progressive burning zone and burns substantially gas-free, is safe to handle, is resistant to moisture and degradation over time, can be incorporated within the confines of existing detonator shells, and poses no environmental hazards.
