DEFLAGRATION AND DEFLAGRATION LIMITS OF SINGLE CRYSTALS OF AMMONIUM PERCHLORATE
Abstract
Using a new technique, the deflagration pressure limit was measured by imposing a known linear temperature gradient along the length of the ammonium perchlorate sample and igniting the warmer end. The pressure was adjusted so that the flame would not propagate through the entire solid, and the length remaining unburned determined the limiting solid temperature corresponding to the set pressure. The AP single crystal deflagration rates were measured using high-speed motion photography and were essentially the same in helium and nitrogen ambient atmospheres. In direct contrast to the catalytic effect of KMnO4 on AP thermal decomposition, a preliminary study showed that 0.4-2.0 mole % KMnO4 isomorphously substituted into the AP crystal lattice prevented deflagration from occurring.
