The aerosol releasing substrate also contains a gelling agent for gelling the aerosol releasing substrate and a degradation preventing and/or thickening stabilizer. The method includes the steps of: a) producing the aerosol releasing substrate and b) pressing the aerosol releasing substrate with pressure and heat and by using a mold into a desired shape. An aerosol releasing substrate for use in a heat-not-burn device is an air permeable compressed mass and includes tobacco particles and/or an inhalable agent, a gelling agent, a degradation preventing and/or thickening stabilizer, as well as 20-70% aerosol former. ## Claims ### Claim 1 An aerosol releasing substrate for use in a heat-not-burn device, the aerosol releasing substrate being air permeable and comprising: at least one of tobacco particles or an inhalable agent, the at least one of the tobacco particles or the inhalable agent containing at least one of a stimulant or a flavor, a gelling agent for gelling the aerosol releasing substrate, at least one of a degradation preventing or thickening stabilizer, and an aerosol former included in an amount ranging from 20% to 70% by weight of the aerosol releasing substrate, wherein the aerosol releasing substrate is an agglomerated granular mass. ### Claim 2 (depends on 1) The substrate according to claim 1, wherein the gelling agent is a non-protein containing polysaccharide. ### Claim 3 (depends on 1) The substrate according to claim 1, wherein the aerosol former comprises at least one of glycerol, propylene glycol, ethanol, or water. ### Claim 4 (depends on 1) The substrate according to claim 1, wherein the aerosol former comprises propylene glycol and glycerol, and a ratio of the propylene glycol to the glycerol is between 80:20 and 20:80. ### Claim 5 (depends on 1) The substrate according to claim 1, wherein the aerosol releasing substrate has a sheet shape. ### Claim 6 (depends on 5) The substrate according to claim 5, wherein the sheet comprises grooves or recesses on at least one side of the sheet. ### Claim 7 (depends on 1) The substrate according to claim 1, wherein the aerosol releasing substrate has a thickness greater than 0.1 mm and smaller than 5 mm. ### Claim 8 (depends on 7) The substrate according to claim 7, wherein the aerosol releasing substrate has a width greater than 5 mm and smaller than 30 mm, and a length greater than 5 mm and smaller than 30 mm. ### Claim 9 (depends on 1) The substrate according to claim 1, wherein the gelling agent is included in an amount greater than 2% and smaller than 12% by weight of the aerosol releasing substrate. ### Claim 10 (depends on 1) The substrate according to claim 1, wherein the at least one of the degradation preventing or thickening stabilizer is included in an amount greater than 8% and smaller than 30% by weight of the aerosol releasing substrate. ### Claim 11 (depends on 1) The substrate according to claim 1, wherein the at least one of the degradation preventing or thickening stabilizer comprises cellulose or a cellulose derivate. ### Claim 12 (depends on 1) A method of using the substrate according to claim 1, comprising: heating the substrate by an oven at volatilization temperatures of the aerosol former in a heat-not-burn device to deliver aerosol. ### Claim 13 (depends on 1) The substrate according to claim 1, wherein the aerosol releasing substrate comprises particles having a size of greater than 0.1 mm. ### Claim 14 (depends on 13) The substrate according to claim 13, wherein the size of the particles ranges from 0.7 mm to 2 mm. ### Claim 15 (depends on 13) The substrate according to claim 13, wherein the aerosol releasing substrate comprises interstices between the particles. ### Claim 16 (depends on 1) The substrate according to claim 1, wherein a paper sheet layer is wrapped around the aerosol releasing substrate. ### Claim 17 (depends on 16) The substrate according to claim 16, wherein the paper sheet layer has a grammage greater than 5 g/m2. ### Claim 18 (depends on 16) The substrate according to claim 16, wherein the paper sheet layer has an air permeability above 1,100 l/m2. ### Claim 19 (depends on 1) The substrate according to claim 1, wherein the gelling agent comprises at least one of gellan gum, lecithin, agar, or a mixture thereof.
