A susceptor is a material that can be heated by penetration of a changing magnetic field, such as an alternating magnetic field. Since the susceptor may be an electrically conductive material, penetrating a changing magnetic field causes inductive heating of the susceptor by resistive heating as a result of electrical eddy currents. Since the susceptor may be a magnetic material, magnetic hysteresis heating of the susceptor occurs when a changing magnetic field penetrates it. Because the susceptor can be both electrically conductive and magnetic, the susceptor can be heated by both heating mechanisms. A device configured to generate a changing magnetic field is referred to as a magnetic field generator.

The susceptor may comprise a ferromagnetic metal such as iron or an iron alloy such as steel or iron nickel alloy. Some examples of ferromagnetic metals include 400 series stainless steel, such as grade 410 stainless steel, or grade 420 stainless steel, or grade 430 stainless steel, or similar grades of stainless steel. Alternatively, the susceptor may comprise a suitable non-magnetic, especially paramagnetic conductive material such as aluminum. In paramagnetic conducting materials, inductive heating occurs only by resistive heating due to eddy currents. Alternatively, the susceptor may include a non-conductive ferromagnetic material, such as a non-conductive ferromagnetic ceramic. In this case, heat is generated only by hysteresis losses. The susceptor is either Phytherm 230 (with a composition (% by weight = % by weight) of 50 wt % Ni, 10 wt % Cr and the balance Fe) or Phytherm 260 (with a composition of 50 wt % Ni, 9 wt % Cr and the balance Fe). case) may include commercial alloys such as

The aerosol-generating material (a) forms a slurry comprising the components of the aerosol-generating material or their precursors, (b) forms a layer of the slurry, (c) cures the slurry to form a gel, and (d) dries. It can be formed by forming an aerosol generating material.

(b) Forming the layer of slurry typically includes spraying, casting or extruding the slurry. In examples, the slurry layer is formed by electrospraying the slurry. In examples, the slurry layer is formed by casting the slurry.

In some examples, (b) and/or (c) and/or (d) occur at least partially simultaneously (e.g., during electrospraying). In some examples, (b), (c), and (d) occur sequentially.

In some examples, the slurry is applied to the support. The layer may be formed on the support.

In examples, the slurry includes a gelling agent, an aerosol former material, and an active agent. The slurry may include these ingredients in any of the ratios given herein in relation to the composition of the aerosol generating material. For example, the slurry may include (on a dry weight basis):

- a gelling agent and optionally a filler, wherein the combined amount of gelling agent and filler is about 10 to 60 wt% of the slurry;

- aerosol former material in an amount of about 40 to 80 wt% of the slurry; and

- Optionally, active material in an amount of up to about 20 wt% of the slurry.

Step (c) of curing the gel may include supplying a curing agent to the slurry. For example, the slurry may include sodium, potassium, or ammonium alginate as a gel precursor, and a curing agent containing a calcium source (e.g., calcium chloride) may be added to the slurry to form a calcium alginate gel.

Suitably, the total amount may be from about 1 wt%, 2.5 wt% or 4 wt% to about 4.8 wt% or 4.5 wt%. The inventors have discovered that adding too little curing agent results in an aerosol-generating material that does not stabilize the aerosol-generating material components and can cause these components to fall out of the aerosol-generating material. The inventors have discovered that adding too much curing agent makes the aerosol-generating material very sticky and consequently poor handling.

If the aerosol-generating material does not contain tobacco, higher amounts of hardener may need to be applied. Accordingly, in some cases, the total amount of curing agent may be 0.5 to 12 wt%, for example, 5 to 10 wt%, calculated on a dry weight basis. Suitably, the total amount may be from about 5 wt%, 6 wt%, or 7 wt% to about 12 wt% or 10 wt%. In this case, the aerosol generating material will generally not include any tobacco.

In examples, supplying the curing agent to the slurry includes spraying the curing agent onto the slurry, such as the top surface of the slurry.

Alginate salts are derivatives of alginic acid, typically high molecular weight polymers (10 to 600 kDa). Alginic acid is a copolymer in which β-D-mannuron (M) and α-L-guluronic acid (G) units (blocks) are linked by (1,4)-glycosidic bonds to form a polysaccharide. When calcium cations are added, the alginate cross-links to form a gel. Alginate salts with high G monomer content were found to form gels more easily when a calcium source was added. Accordingly, in some cases, the gel precursor is an alginate salt wherein at least about 40%, 45%, 50%, 55%, 60% or 70% of the monomer units of the alginate copolymer are α-L-guluronic acid (G) units. may include.
