Incendiary pellet

Italian Incendiary Shell. Italian antiaircraft incendiary pellet projectiles, in WWlI, consisted of a 76 or 90-caliber shell loaded with a number of incendiary-filled cylindrical pellets. The pellets were ignited by a flash from a central flash tube. A delay mixture activated a secondary explosive in the base which broke the shell into flak. Composition of the incendiary filling is not given in Ref 16...

Igniters. A pellet composed of 26.5% K. perchlorate, 16.6% Ba nitrate, 53,9% 50/50 Zr/Ni alloy, and 3.0% et cellulose can be used to ignite solid propint grains (Ref 25), A series of mixts of K perchlorate with powd metals and other oxidizable mat were examined as substitutes for BikPdr as a gun primer. Most of the mixts tested were found to be satisfactory and to be compatible with brass and other metals (Ref 9) Incendiary Compositions. Stoichiometric mixts of K perchlorate with metals and oxidizable mat have been proposed as incendiaries of the Thermit type and have heats of reaction as follows Al dust 2504, powd Mg 2429. red P 1477, powd S 705 and powd C (lampblack) 1118cal/g (Ref 4). A mixt of 12.5% K perchlorate, 75% powd Zr, and 12,5% of a 50/50 Al/Mg alloy is reported to be a readily-ignited incendiary (Ref 20). Mixts of powd Al and/or powd Fe with K perchlorate with 1.5—2% NC as a binder are also good incendiaries (Ref 35). 

Pellets, slugs or flechettes made of U have very good powers of penetration. However, U is softer than steel so that in the process of penetrating an armored steel plate it is partially pulverized. Since in this form U is pyrophoric (self-igniting), such projectiles have an incendiary as well as a penetrating effect. According to one account of flechettes made of depleted U ... 

Bomb Burster, AN-M13., designed for use (in conjunction with igniter AN-M9) in incendiary bomb AN-M47A4, consists of a plastic tube 0.45-inches in diam, 36.0-in long, provided at each end with a soft brass cup. It is filled with ca 65 g of TNT and has a Tetryl pellet at each end (Ref 51a, P 5-15)... 

Japanese 120mm Incendiary Projectile contained 48 steel pellets embedded in a canister filled with white phosphorous. Each pellet had an annular cavity to increase the amount of phosphorous that could be retained by each pellet. The shell was exploded by means of a bursting charge of HE, fired by a point-detonating fuse...

Incendiary Stick Grenade had light steel cylindrical body with hemispherical ends and wooden handle threaded into the base. Length of body 13.2 inches, diam 2.1 inches and length of handle 5.3 inches. The body was filled with 41 rubber pellets, each impregnated with a soln of WP in carbon disulfide. The pellets were scattered by means of a small central burster chge.
