The present disclosure provides an aerosol generating component containing a substrate impregnated with one or more aerosol forming materials, the substrate including a cellulosic material substantially free of sulfur compounds, and further including one or more of a tobacco pulp, an aqueous tobacco extract, a filler, and a binder. Further provided is an aerosol delivery device including the aerosol generating component. Such devices utilize electrically generated heat or combustible ignition sources to heat the aerosol forming materials, providing an inhalable substance in the form of an aerosol.

An aerosol-generating article for producing an inhalable aerosol when heated is provided, the aerosol-generating article including: a rod of aerosol-generating substrate, including: a plurality of elongate tubular elements of homogenised tobacco material assembled such that the plurality of elongate tubular elements extend in a longitudinal direction, and a wrapper circumscribing the plurality of elongate tubular elements, the plurality of elongate tubular elements being aligned substantially parallel to one another within the rod of aerosol-generating substrate.

A composite heat source for use in a smoking article is provided, including a non-combustible porous ceramic matrix; and a particulate combustible fuel embedded within the non-combustible porous ceramic matrix. The non-combustible porous ceramic matrix is formed from one or more particulate materials having a median D50 particle size at least five times less than the median D50 particle size of the particulate combustible fuel. Preferably, the non-combustible porous ceramic matrix includes one or more transition metal oxides.

Smoking articles are disclosed herein. In one aspect, a smoking article includes a heat source configured to generate heat upon ignition thereof, a first substrate material having an aerosol precursor composition associated therewith and a first end being fixedly engaged with the heat source, and an aerosol delivery component having opposed first and second ends, the first end of the aerosol delivery component being engaged with the second end of the first substrate material. In some aspects, the aerosol delivery component includes a second substrate material having the aerosol precursor composition associated therewith and being disposed about the first end of the aerosol delivery component and a tobacco material disposed between the second substrate material and the mouthpiece, the aerosol precursor composition associated with the first and second substrate materials being configured to produce an aerosol in response to the heat generated by the ignited heat source.

A combustible heat source for an aerosol-generating article, the combustible heat source comprising: carbon; an alkaline earth metal peroxide ignition aid; and a binding agent comprising a combination of carboxymethyl cellulose and at least one additional cellulose ether. Preferably, the at least one additional cellulose ether is selected from the group consisting of ethyl cellulose, methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, and hydroxypropyl methylcellulose.

A tobacco composition including tobacco material and an aerosol former material. The tobacco material includes a leaf tobacco having sugars and nicotine in a weight ratio of between about 8:1 and about 20:1, wherein said leaf tobacco having sugars and nicotine in a weight ratio of between about 8:1 and about 20:1 is present in the tobacco material in an amount of at least 5% by weight of the tobacco material.

A carrier, apparatus and method for making an aerosol precursor liquid suitable for aerosolized delivery by a device such as an electronic cigarette. A carrier is fluid permeable and comprises a tobacco-derived medium for carrying a functional component, the medium being configured to release the functional component into a fluid to provide an aerosol precursor liquid infused with the functional component. A method for mixing an aerosol precursor liquid for aerosolized delivery of a functional component by an aerosol delivery device comprises bringing the tobacco-derived medium carrying the functional component into contact with fluid and allowing the fluid to saturate the medium to thereby cause the medium to release the functional component into said fluid to form an aerosol precursor liquid infused with the functional component. A receptacle comprising a chamber for the carrier is provided for mixing the aerosol precursor liquid. Example functional components include nicotine and nicotine salts.

A combustible heat source (4) for an aerosol-generating article (2) comprises carbon and calcium peroxide. The calcium peroxide has a purity of greater than or equal to about 90 percent. A method of producing a combustible heat source for an aerosol-generating article, the method comprising the steps of: mixing a carbon material and calcium peroxide having a purity of greater than or equal to about 90 percent; forming the mixture of the carbon material and the calcium peroxide into an elongate rod; and drying the elongate rod.

A method of producing a combustible heat source for an aerosol-generating article, the method comprising: forming a combustible heat source comprising carbon and a binding agent, wherein the binding agent comprises polyvinyl alcohol; and heating the formed combustible heat source at a temperature of at least about 90 degrees Celsius for a period of at least about 45 minutes.

A flavor inhaler includes a tubular holder that extends from a mouthpiece end toward a distal end, a flavor source that is provided in the holder, and a combustion type heat source that is provided at the distal end, and includes a protruding portion protruding from the distal end and a flavorant carried on the protruding portion.
