ABSTRACT:
Disclosed is a method for the prevention of the formation of ammonia as a product in the reaction of hydrazine and a halogen oxidizer used in a liquid-propelled rocket engine and in chemical laser pumping systems. The method employs vanadium pentafluoride as an additive up to about 1% to the halogen oxidizer to thereby shift the equilibrium of the reaction between the hydrazine and the halogen oxidizer so that no ammonia is produced.
