Abstract: An aerosol-generating article for producing an inhalable aerosol upon heating comprises a plurality of components including an aerosol-forming substrate. The aerosol-forming substrate is in the form of a hollow tubular segment defining a substrate cavity extending between an upstream end of the aerosol-forming substrate and a downstream end of the aerosol-forming substrate. The aerosol-forming substrate comprises a plurality of thermally conductive particles and an aerosol-former. The combination of tubular geometry and thermally conductive particles allows swifter time to first puff, improved efficiency of aerosol extraction and lighter weight of aerosol-generating article.
