This paper conducts perimental studies of the six new and energetic catalysts in the screw extruded energetic propellant with low signatrue. It is discovered that these catalysts are not only energetic, but also high activated. By these catalysts,the difficult technical problem about inferior burning rate′s propert of proellant with high RDX contect is successfully solved. These catalysts lead to the important roles in studing of energetic propellant with low signature.
