NOVELTY - Plant particle with high heat conductivity coefficient comprises 30-70 wt.% crushed plant material, 10-40 wt.% aerosol-forming substance, 3-15 wt.% water, 0.0-20 wt.% adhesive, 0.05-0.5 wt. high heat-conducting substance powder. USE - Plant particle with high heat conductivity coefficient (all claimed). ADVANTAGE - The particle has increased the smoke amount of the granular heated cigarette, has greatly improved the heat conductivity of the plant particles, has improved the adding amount, and has improved the thermal conductivity without further obvious help effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a method for preparing plant particles with a high heat conductivity coefficient, which involves mixing the high-heat conducting substance powder with a portion of the crushed plant material to obtain a mixture, then mixing the mixture with the rest of the crushed plant material, then adding aerosol forming substance and water, adding and/or not agglomerate, stirring and standing at room temperature to make the liquid component fully absorbed by the crushed plant material, then using screw extrusion rolling method, rotary extrusion whole grain method and/or swing extrusion method to prepare the plant particles with high heat conductivity coefficient, the contents of substances and substances contained in the plant particles are 30-70 wt.% crushed plant material, 10-40 wt.% aerosol-forming substance, 3-15 wt.% water, 0.0-20 wt.% adhesive, 0.05-0.5 wt. high heat-conducting substance powder; and 2. a method for improving the heat conductivity of plant particles, which involves using plant particles with a high heat conductivity coefficient.
