## Abstract An explosion occurred recently during the operation of a grinder that had been used to process potassium chlorate and then thiourea. As part of our investigation of this accident we determined the mechanical sensitiveness of mixtures containing these components and showed that they can

&InSrfiduction
The heat af reaction is ZUI important parameter of a pyrotechnic composition, being One c-f rhe !&actors which controol the maximum temperature attained during combustion. This is especially true with pyrotechnic c~mpasitions containing pr~taAm chlorate which are used to vaporize organic materials. The latter are decomposed at high temperatures and are thus sensitive to the mount of heat evolved. ?he &at of reaction m my be used as one of the eritcria B: selecting z fEeI. and it Is tmpotiant in any mathematical treatment describing the rate of burning. Ii may also be used

The antimony/potassium permanganate pyrotechnic system is not gasless although it is used in sealed electric delay detonators. Burning rates of identical compositions vary according to the extent to which the system is confined. The variation is especially marked for the high fuel compositions which
The Sb/KMnO4 pyrotechnic system has been used as a starting point for introducing modifications, other than those of composition or fuel particle size, aimed at reducing the burning rate to as low a value as possible, for use in longperiod delay detonators. Both inert and reactive additives have bee
