Abstract

The ignition by electrically heated coil of two smoke generators containing hexachloroethane and silumin, one of which also contains zinc oxide, has been investigated. The physical conditions of consolidation, that is pressing load (between 7.9 × 10^6^ kg/m^2^ and 3.1 × 10^7^ kg/m^2^) and diameter of container (between 1.27 cm and 2.54 cm), have been shown to have no effect on the ease of ignition of each mixture. Addition of zinc oxide increases the minimum temperature of ignition from about 443 K to about 973 K and the minimum heating rate for ignition from about 2.5 watt to about 8 watt. The effect of zinc oxide is believed to be chemical rather than physical in nature.
