Claims
- 1. A main energetic ingredient filler useful for propellant-based munitions, comprising:filler particles having a fine particle size of less than about ten micrometers diameter; and a thin coating of graphite on said filler particles in an amount such that the weight of said graphite is less than about two percent of the weight of said filler particles.
- 2. The filler of claim 1, wherein said filler particle size has an average particle diameter ranging from about two to about eight micrometers.
- 3. The filler of claim 1, wherein said graphite comprises about one percent by weight of said filler particles.
- 4. The filler of claim 1, wherein filler is selected from the group consisting of CL-20, TNAZ, NQ, RDX, HMX and mixtures thereof.
- 5. The filler of claim 1, wherein said filler is CL-20 ground to an average particle diameter of about five to ten micrometers.
- 6. The filler of claim 1, formed into a propellant including a binder and a plasticizer.
- 7. A main energetic ingredient filler useful for propellant-based munitions, comprising:filler particles having a fine particle size of about six to seven micrometers diameter, said filler being selected from the group consisting of CL-20, TNAZ, NQ, RDX, HMX and mixtures thereof; and a thin coating of graphite on said filler particles in an amount such that the weight of said graphite is about one percent of the weight of said filler particles.
- 8. The filler of claim 7, wherein said filler is CL-20, said filler being formed into a propellant including a binder and a plasticizer.
- 9. A method of making a main energetic ingredient filler useful for propellant-based munitions, comprising the steps of:grinding filler particles to a fine particle size of less than about ten micrometers diameter; and coating graphite on said filler particles in an amount such that the weight of said graphite is less than about two percent of the weight of said filler particles.
- 10. The method of claim 9, wherein said filler particle size has an average particle diameter ranging from about two to about eight micrometers.
- 11. The method of claim 9, wherein said graphite comprises about one percent by weight of said filler particles.
- 12. The method of claim 9, wherein filler is selected from the group consisting of CL-20, TNAZ, NQ, RDX, HMX and mixtures thereof.
- 13. The method of claim 9, wherein said filler is CL-20 which is ground to an average particle diameter of about five to ten micrometers.
- 14. The method of claim 9 comprising the additional step of forming said filler into a propellant including a binder and a plasticizer.
