A smoking article with an electrochemical heat source is disclosed. The non-combustion heat source includes at least two metallic agents capable of interacting electrochemically with one another, such as magnesium and iron or nickel. The metallic agents may be provided in a variety of forms, including a frozen melt, a bimetallic foil, wire of a first metal wrapped around strands of a different metal, and a mechanical alloy. The metallic agents may be in the form of a powder filling a straw, or small particles extruded with a binder or pressed to form a rod. Preferably, the heat source is self-extinguishing if ignited. The powder filled straw or rod may be placed in a heat chamber surrounded by tobacco. An electrolyte solution contacts the metallic agents in the heat chamber to initiate the electrochemical interaction, generating heat which in turn volatilizes the nicotine and flavor materials in the tobacco. Preferably, any gases from the heat chamber are directed away from air intake holes through which air enters the smoking article.

The present invention relates to a substrate material having a decreased retentive capacity for use as a carrier for aerosol forming materials in smoking articles which smoking articles are capable of producing substantial quantities of aerosol, both initially and over the useful life of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products or sidestream aerosol. Thus, the substrate material of the present invention when used with preferred smoking articles is able to provide the user with the sensations and benefits of cigarette smoking without burning tobacco. In addition, the article may be made virtually ashless so that the user does not have to remove any ash during use. Preferred smoking articles which employ the substrate material of the present invention have a short combustible carbonaceous fuel element, alumina or carbon substrate modified in accordance with the present invention bearing an aerosol forming substance, an efficient insulating means, and a relatively long mouth end piece. The fuel element is provided with a plurality of longitudinally extending passageways which act to control the heat transferred from the burning fuel element to the aerosol generating means, thus preventing the thermal degradation of the aerosol former.

The viscosity of phosphate rock slurries is reduced by incorporating in the slurry both sodium tripolyphosphate and an alkaline material, particularly sodium hydroxide. The combined amount of these two materials required to achieve a given viscosity reduction is significantly lower than the weighted average of the amounts required for each to produce individually the same viscosity reduction. The defined alkaline materials, other than sodium hydroxide, are sodium carbonate, ammonium hydroxide and potassium hydroxide.

The dusting and segregation of the glass batch during the manufacture of opal borosilicate glass can be reduced by adding the phosphorus values to the glass batch as phosphoric acid, and calcium values as limestone, calcium carbonate or calcium oxide.

Cigarettes include tobacco-containing smokable material wrapped in a low porosity paper wrapper. The smokable material includes an intimate mixture of tobacco extract, pyrolyzed alphacellulose, agglomerated calcium carbonate particles, glycerin and carboxymethylcellulose. The agglomerated calcium carbonate particles are provided by providing an agglomerated matrix of calcium carbonate particles and organic binding agent, and calcining the organic binding agent. The resulting agglomerated matrix includes particles of calcium carbonate within a carbonaceous binding material. Such cigarettes yield low levels of incomplete combustion products and generate low levels of visible sidestream smoke.

The present invention is directed to cigarettes and other smoking articles which contain a catalytic composition, preferably as part of the fuel element, that substantially decreases the amount of carbon monoxide contained in the mainstream smoke during smoking. The present invention also relates to the catalyst-containing carbonaceous fuels themselves, as well as to methods of making such carbonaceous fuels. Fuel elements which contain a catalytic composition in accordance with the presentation are especially useful in smoking articles having an aerosol generating means which is physically separate from the fuel element.

Cigarettes have a tobacco rod including smokable material circumscribed by a paper wrapper. The paper wrapper includes a cellulosic base web (e. g. , flax and/or wood pulp fibers) and particles of at least one inorganic filler material. The inorganic filler material includes calcium sulfate, and normally fibers of calcium sulfate having an aspect ratio of about 30.

The present invention relates to an improved insulating sheet material and to cigarettes and other smoking articles which employ the insulating sheet material as one or more components thereof. The improved insulating material is particularly useful in smoking articles having a fuel element and a physically separate aerosol generating means, e. g. as an insulating member for insulating the fuel element. In general, the sheet material of the present invention is formable without the use of any organic binder and comprises an inorganic fibrous material such as calcium sulfate fibers, calcium sodium phosphate fibers, or mixtures thereof, and a relatively small amount of highly refined cellulose-based fibers such as wood pulp.
