Abstract

5 A solid propellant for rocket propulsion systems or gas generators compri 35 to 80 wt. % ammonium nitrate (AN) with an average particle size of 5 to 200 .mu.m, which is phase-stabilized (PSAN) by chemical reaction with Cu0 or Zn0, 15 to 50 wt. % of a binder system of a binder polymer and an energy-rich plasticizer, as well as 0.2 to 5.0 wt. % of a burning moderator of vanadium/molybdenum oxide as an oxide mixture or mixed oxide.
