Incendiary compositions of magnesium and fluoroalkyl phosphate esters

An incendiary composition consisting essentially of particulate magnesium, an inorganic oxidizer and a mono- or di-fluoroalkyl phosphate ester or mixture of said fluoroalkyl phosphate esters wherein the alkyl group or groups are all fluoroalkyl groups and have 5 to 11 carbon atoms.

An incendiary composition containing as its essential active ingredients particulate magnesium and mono- and/or di-fluoroalkyl phosphate ester wherein the alkyl groups are all fluoroalkyl groups and each has 5 to 11 carbon atoms.

An incendiary composition containing 35 to 75% by weight of particulate magnesium and 25 to 65% by weight of mono- and/or di-fluoroalkyl phosphate ester wherein the alkyl groups are all fluoroalkyl groups and each has 5 to 11 carbon atoms, based on the total weight of magnesium and phosphate ester in said composition.

An incendiary composition comprising 28% to 35% by weight of mono- and/or di-fluoroalkyl phosphate ester wherein the alkyl groups are all fluoroalkyl groups and each has 5 to 11 carbon atoms, 9% to 14% by weight of ferric oxide, 24% to 32% by weight of particulate magnesium, 10% to 15% by weight of particulate silicon, and 10% to 25% by weight of potassium perchlorate.

In a process for making an incendiary composition by mixing particulate magnesium, a fluorocarbon oxidizer, an inorganic oxidizer and a heat-transfer promoter, casting the resulting mixture in a desired configuration and heating the cast composition to cure it, the improvement which comprises using as the fluorocarbon oxidizer one or more liquid mono- and/or di-fluoroalkyl phosphate esters wherein the alkyl groups are all fluoroalkyl groups and each has from 5 to 11 carbon atoms.
