Grain aluminum nitrate

API), has the lead point filler replaced by an incendiary composition. It is also used primarily against aircraft. The API bullet is similar to (I), except that the incendiary is ahead of the steel core. The cal. 50 API bullet contains 15 grains of the incendiary mixture consisting of barium nitrate and aluminum-magnesium powder. This mixture ignites on impact... 

Of even more recent interest are flares or rocket grain ingredients that are apt to produce a large number of ions from the exposure of alkali metal to high temperature. Presence of alkali metal additives in rocket exhaust at 3000 K is said to cause in excess of ICP ions/cm , and from mixtures of aluminum with the nitrates of cesium or ptotass him, electron densities of the order of 10 /cm have been reported. " Shidlovsky quotes from Reference 250 that a cesium plasma may be obtained frc n a mixture of aluminum and cesium perchlorate. The sutqect of the direct dispersion of alkali metals and other substances at Wgh altitude will be discussed in the concluding passages to Chapter 19. 

Compositions of highest heat output using boron, aluminum, and titanium or zirconium, with oxidizers such as potassium nitrate or perchlorate, are not normally needed in strictly pyrotechnic lire transfer, but they are important in the initiation of solid propellants, be it for small items such as gas cartridges or for larger grains. Formulas 182, 183, and 184 are some of the better-known examples.

A simple explosive like black powder is a mixture. The oxygen source is potassium nitrate, and the fuel is charcoal with sulfur added to aid the burning. Hour and air is even a simpler explosive but powerful enough to blow a grain elevator apart. Even the most modem explosives still use a partial mixture, such as adding a reactive powdered metal like magnesium or aluminum to the explosive.
