ABSTRACT:
An iron carbide heat source, particularly useful in smoking articles, is provided. The iron carbide particles making up the heat source have ignition temperatures that are substantially lower than conventional carbon particles normally used in carbonaceous heat sources, while at the same time provide sufficient heat to release a flavored aerosol from a flavor bed for inhalation by the smoker. In a preferred embodiment, the iron carbide heat source of this invention is substantially cylindrical in shape and has one or more fluid passages therethrough. Upon combustion, the heat source produces substantially no carbon monoxide.
