  • Method for producing metal carbide heat sources
    Patent number: 5247949
    Abstract: This invention relates to a heat source comprising metal carbide and a method for preparing the same using a reducing/carbidizing atmosphere. The metal carbide heat sources of this invention 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. Upon combustion, the heat sources produce substantially no carbon monoxide.
