There is described an aerosol-forming substrate for use in combination with an inductive heating device. The aerosol-forming substrate comprises a solid material capable of releasing volatile compounds that can form an aerosol upon heating of the aerosol-forming substrate, and at least a first susceptor material for heating of the aerosol-forming substrate. The first susceptor material has a first Curie-temperature and is arranged in thermal proximity of the solid material. The aerosol-forming substrate comprises at least a second susceptor material having a second Curie-temperature which is arranged in thermal proximity of the solid material. The first and second susceptor materials have specific absorption rate (SAR) outputs which are distinct from each other. Alternatively or in addition thereto the first Curie-temperature of the first susceptor material is lower than the second Curie-temperature of the second susceptor material, and the second Curie-temperature of the second susceptor material defines a maximum heating temperature of the first and second susceptor materials. There is also described an aerosol-delivery system.
An aerosol-forming substrate for use in combination with an inductive heating device, the aerosol-forming substrate comprising a solid material capable of releasing volatile compounds that can form an aerosol upon heating of the aerosol-forming substrate, and at least a first ferromagnetic susceptor material for heating the aerosol-forming substrate, the first ferromagnetic susceptor material having a first Curie-temperature and being arranged in thermal proximity of the solid material, the aerosol-forming substrate comprising at least a second ferromagnetic susceptor material having a second Curie-temperature and being arranged in thermal proximity of the solid material, the first and second ferromagnetic susceptor materials having specific absorption rate (SAR) outputs which are distinct from each other and/or the first Curie-temperature of the first ferromagnetic susceptor material being lower than the second Curie-temperature of the second ferromagnetic susceptor material, and the second Curie-temperature of the second ferromagnetic susceptor material defining a maximum heating temperature of the first and second ferromagnetic susceptor materials, wherein the first Curie-temperature is a temperature at which the magnetic properties of the first susceptor material changes from a ferromagnetic phase to a paramagnetic phase, and where the second Curie-temperature is a temperature at which the magnetic properties of the second susceptor material changes from a ferromagnetic phase to a paramagnetic phase.
