摘要： A carbonaceous heat source comprising metal oxides and methods for making such heat source are provided. The heat source has an ignition temperature substantially lower than conventional carbonaceous heat sources, while at the same time produces virtually no carbon monoxide upon combustion. The heat source is prepared by pre-forming the carbon and binder materials into a desired shape, and then treating the shape with a sol containing metal oxide precursors. The metal oxide precursors are deposited in the pre-formed carbon shape. Further treatment converts the deposited metal oxide precursors into metal oxide.

摘要： A plurality of resistive heating elements and conductive elements are screenprinted onto a ceramic substrate to form a heater having multiple resistive heating elements. Slots formed between adjacent resistive heating elements members provide air gaps to thermally insulate each heating element from neighboring elements. Gold-plated leads provide low contact resistance for receiving power from a battery for energizing each of the resistive heating elements.

摘要： An improved carbonaceous heat source suitable for use in a smoking article is provided. The heat source is formed by mixing a carbon component, a catalytic precursor and a binder, forming the mixture into a shape, and supplying heat to the mixture. Upon combustion of the heat source, the catalytic precursor forms a catalyst that converts carbon monoxide produced during combustion of the heat source into a benign substance.
