US Patent 10952469 Aerosol-forming substrate and aerosol-delivery system

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 is arranged in thermal proximity of the solid material. The aerosol-forming substrate further comprises at least a second susceptor material having a second Curie-temperature which is lower than a predefined maximum heating temperature of the first susceptor material. There is also described an aerosol-delivery system.
