In order to study the formula and preparation of a new type safe ignition compositions, based on the typical formula of boron/potassium nitrate (B/KNO₃), the ultra-fine KNO₃ was used to improve its ignition performance, and then the B/KNO₃ molding powder was obtained by manual mixing while adding phenol formaldehyde resin or fluorine rubber as the binder. The test of flame sensitivity indicates that the sensitivity will rise with the increase of KNO₃ mass content, especially the B/KNO₃ (50/50) adding 2.5% phenol formaldehyde resin as additive binder is more sensitive, but the electrostatic sensitivity test shows that sensitivity will fall with the decrease of KNO₃ mass content. When the mass ratio of B/KNO₃ keeps constant, the ignition powder adding fluorine rubber binder is less sensitive than that of phenol formaldehyde resin.
