Claim 8:
9. A system for heating an aerosol-forming substrate to a predefined maximum temperature, the system comprising:
an aerosol-forming article comprising the aerosol-forming substrate and first and second susceptor materials each in thermal proximity to the aerosol-forming substrate, wherein the first and second susceptor materials are different from each other and have different geometrical configurations than one another;
a cavity configured to receive the aerosol-forming article;
an inductive heating device; and
circuitry operably coupled to the inductive heating device and configured to:
activate the inductive heating device so as to inductively heat the first susceptor material such that the first susceptor material heats the aerosol-forming substrate to form an aerosol;
detect a first phase-change of the second susceptor material during the inductive heating, the first phase-change occurring at the predefined maximum temperature; and
responsive to detecting the first phase-change of the second susceptor material, deactivate the inductive heating device to stop inductively heating the first susceptor material.
