Abstract
Abstract There is described an incendiary composition consisting essentially of by weight 20-40 percent magnesium powder, 30-60 percent metallic oxide and the remainder of elastomeric polysiloxane which serves as a binder the amount of polysiloxane being at least 10 percent. A second type of composition consists of 20-50 percent magnesium powder, 20-30 percent polytetrafluoroethylene in particulate form, and the remainder of elastomeric polysiloxane. A third type of composition consists of mixtures of the first and second types in proportions according to the desired specific gravity of the incendiary.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
55 words
In combination with an explosive charge an incendiary composition consisting essentially of by weight 20 to 40 percent magnesium powder, 30 to 60 percent metallic oxide chosen from the group consisting of Fe 3 O 4 , MnO 2 and TiO 2 and the remainder of elastomeric polysiloxane, said remainder being at least 10 percent.
Claim 2
Dependent Claim
55 words
In combination with an explosive charge an incendiary composition consisting essentially of by weight 20 to 40 percent magnesium powder, 30 to 60 percent metallic oxide chosen from the group consisting of Fe 3 O 4 , MnO 2 and TiO 2 and the remainder of elastomeric polysiloxane, said remainder being at least 10 percent.
Claim 3
Dependent Claim
44 words

Claim 4
Dependent Claim
49 words
In combination with an explosive charge an incendiary composition consisting essentially of by weight 20 to 50 percent magnesium powder, 20 to 30 percent polytetrafluoroethylene in particulate form and the remainder of elastomeric polysiloxane as a binder for said magnesium and polytetrafluoroethylene, said remainder being at least 10 percent.
Claim 5
Dependent Claim
49 words
In combination with an explosive charge an incendiary composition consisting essentially of by weight 20 to 50 percent magnesium powder, 20 to 30 percent polytetrafluoroethylene in particulate form and the remainder of elastomeric polysiloxane as a binder for said magnesium and polytetrafluoroethylene, said remainder being at least 10 percent.
