▎ 摘　　要

NOVELTY - The substrate has carbon particles of 10 to 90 wt.%, aerosol former of 7 to 60 wt.%, fibers 2 to 20 wt.%, and a binder of 2 to 10 wt.% on a dry weight basis. Each of the carbon particles contains graphite, expanded graphite, graphene, carbon nanotubes, charcoal, and/or diamond. The carbon particles include a particle size distribution with a volume D10 particle size of 1-20 μ m. The volume particle size is ≯ 50 times the particle size, where the substrate comprises water of 1-20 wt.%. USE - Aerosol-forming substrate for an aerosol-generating system (claimed). ADVANTAGE - The substrate utilizes thermally conductive particles to increase thermal conductivity of the substrate so as to provide a more even temperature distribution throughout the substrate during use, thus resulting in a greater proportion of the substrate reaching a sufficiently high temperature to release volatile compounds and providing a higher usage efficiency of the substrate. The increased thermal conductivity of the substrate allows allow a heater or a heating blade configured to heat the substrate to operate at a lower temperature, thus requiring less power. The substrate utilizes fibers and a binder to increase a tensile strength of the substrate so as to allow production of a sheet of the substrate which does not easily tear. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a combined aerosol-forming substrate; an aerosol-generating system; and a method for forming an aerosol-forming substrate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of an aerosol- generating article. 10Aerosol-generating article 24Aerosol-cooling element 42Mouthpiece element 50Intermediate hollow section 60Ventilation zone
