Abstract
The present disclosure provides components useful in heating, particularly heating of an aerosol precursor solution so as to vaporize the solution and form an aerosol. The disclosure particularly provides an electrically conductive, porous carbon heater. The heater may be combined with an aerosol precursor transport element that also is formed of carbon. The heater and transport element may form an atomizer that can be useful in an electronic smoking article, such as in a cartridge that is adapted for attachment to a control body. In some embodiments, the disclosure provides a cartridge of an electronic smoking article, the cartridge being formed substantially completely of carbon.
