Abstract
Abstract An incendiary projectile, particularly an armor-piercing projectile, including an incendiary composition constituted of a metal powder admixture as a reducing agent and an inorganic oxidizing agent; and a binding agent for converting these components into a solid form. The oxidizing agent is a nitrate or peroxide of the elements selected from the group consisting of potassium, strontium or barium, the oxidizing and reduction agents being present in about equal parts in the incendiary composition. Binding agents are included in the admixture in a predetermined amount so as to formulate the admixture into a hard-grained agglomerate and to produce a resultant increased impact sensitivity of the incendiary composition.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
In an incendiary projectile, particularly an armor-piercing projectile, including an incendiary composition constituted of a metal powder admixture as a reducing agent and an inorganic oxidizing agent; and a binding agent for converting these components into a solid form, the improvement comprising: the incendiary composition providing for increased sensitivity to impact to spontaneously ignite upon impact against a target without requiring a separate ignition charge, said oxidizing agent being nitrate or peroxide of the elements selected from the group consisting of potassium, strontium or barium, said oxidizing and reduction agents being present in about equal parts in said incendiary composition; and binding agents being included in said admixture in an amount of 1 to 5% by weight so as to formulate said admixture into a hard-grained agglomerate and with a resultant increased impact sensitivity of said incendiary composition.
Claim 2
Dependent Claim
138 words

Claim 3
Dependent Claim
17 words
Incendiary projectile as claimed in claim 1, said binding agent comprising 1.5% by weight of said admixture.
Claim 4
Dependent Claim
17 words
Incendiary projectile as claimed in claim 1 or 2, said binding agent being constituted of chlorinated rubber.
Claim 5
Dependent Claim
18 words
Incendiary projectile as claimed in claim 1 or 2, said binding agent being constituted of a silicon resin.
Claim 6
Dependent Claim
44 words
Incendiary projectile as claimed in claim 1, said incendiary composition including about 40 to 60% by weight of barium nitrate; about 1.5% by weight of said binding agent; and the remainder containing an admixture of aluminum and magnesium powder in a ratio of 1:1.
Claim 7
Dependent Claim
15 words
Incendiary projectile as claimed in claim 5, including about 50% by weight of barium nitrate.
