Note(s) In this sub-class, the words "based on", with reference to explosive compositions, refer to the explosive ingredient present in the largest proportion by weight. This sub-class includes: Compositions which are: Explosive: compositions included are those containing both a fuel and sufficient oxidizer so that, upon initiation, they are capable of undergoing a chemical change of a relatively high rate of speed, resulting in the production of usable force for blasting, firearms, propelling missiles, etc. Thermic: compositions included have (a) a consumable fuel component which consists of any element which is a metal, B, Si, Se or Te, or mixtures, intercompounds, or hydrides thereof; and (b) in combination an oxidant component which is either a metal oxide or a salt (organic or inorganic) capable of yielding a metal oxide on decomposition. Fuels for rocket engines and intended for reaction with an oxidant, excluding air, in order to provide thrust for motive power purposes. For use in affecting the explosion environment, e.g. for neutralising the poisonous gases of explosives, for cooling the explosion gases, etc. Methods or apparatus for preparing or treating such compositions not otherwise provided for. The classification of methods is according to the particular components of the compositions. Methods of using single substances as explosives. [2]
