Abstract 1. A SOLID UNITARY COMPOSITE PROPELLANT GRAIN COMPRISING, IN ADMIXTURE: (1) PASSIVATED LITHIUM METAL WHICH INCREASES IN WEIGHT NO MORE THAN 10 PERCENT FROM THE DRY STATE OVER 12 HOURS IN CONTACT WITH AN ENVIROMENT OF 50 PERCENT RELATIVE HUMIDITY AND 25* C., SAID PASSIVATION BEING ACCOMPLISHED BY A COATING ON LITHIUM WHICH IS CHEMICALLY INSERT TOWARD AND INSOLUBLE IN THE CONSTITUENTS OF THE GRAIN, (2) A LOW-VOLATILITY FLUORINE OXIDIZING AGENT (A) CONTAINING MORE THAN ABOUT 50 PERCENT BY WEIGHT OF FLUORINE WHICH IS BONDED TO CARBON AND NITROGEN ATOMS AND (B) HAVING A HEAT OF REACTION WITH LITHIUM OF NOT LESS THAN ABOUT 100 KILOCALORIES PER GRAM EQUIVALENT OF THE FLUORINE THEREIN, AND (3) A SOLID POLYMERIC BINDER (A) WHICH HAS A MOLECULAR WEIGHT OF NOT LESS THAN ABOUT 10,000 (B) WHICH CONTAINS NO ACTIVE HYDROGEN AND (C) IN WHICH AT LEAST ABOUT 50 PERCENT OF THE ATOMS IN TH BACKBONE ARE CARBON ATOMS, THE OVERALL WEIGHT RATIO OF LITHIUM TO FLUORINE IN THE PROPELLANT GRAIN BEING NOT LESS THAN ABOUT 7:19.
A SOLID UNITARY COMPOSITE PROPELLANT GRAIN COMPRISING, IN ADMIXTURE: (1) PASSIVATED LITHIUM METAL WHICH INCREASES IN WEIGHT NO MORE THAN 10 PERCENT FROM THE DRY STATE OVER 12 HOURS IN CONTACT WITH AN ENVIROMENT OF 50 PERCENT RELATIVE HUMIDITY AND 25* C., SAID PASSIVATION BEING ACCOMPLISHED BY A COATING ON LITHIUM WHICH IS CHEMICALLY INSERT TOWARD AND INSOLUBLE IN THE CONSTITUENTS OF THE GRAIN, (2) A LOW-VOLATILITY FLUORINE OXIDIZING AGENT (A) CONTAINING MORE THAN ABOUT 50 PERCENT BY WEIGHT OF FLUORINE WHICH IS BONDED TO CARBON AND NITROGEN ATOMS AND (B) HAVING A HEAT OF REACTION WITH LITHIUM OF NOT LESS THAN ABOUT 100 KILOCALORIES PER GRAM EQUIVALENT OF THE FLUORINE THEREIN, AND (3) A SOLID POLYMERIC BINDER (A) WHICH HAS A MOLECULAR WEIGHT OF NOT LESS THAN ABOUT 10,000 (B) WHICH CONTAINS NO ACTIVE HYDROGEN AND (C) IN WHICH AT LEAST ABOUT 50 PERCENT OF THE ATOMS IN TH BACKBONE ARE CARBON ATOMS, THE OVERALL WEIGHT RATIO OF LITHIUM TO FLUORINE IN THE PROPELLANT GRAIN BEING NOT LESS THAN ABOUT 7:19.
