ABSTRACT:
This invention relates to a heat source comprising a mixture of metal carbide, metal nitride and metal which undergo a staged ignition process, particularly useful in smoking articles. The metal carbide/metal nitride/metal mixtures making up the heat source have ignition temperatures that are substantially lower than conventional 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. Upon combustion the heat source produces substantially no carbon monoxide or nitrogen oxides.
