Abstract

The inductively heatable tobacco product for aerosol-generation comprises an aerosol-forming substrate containing a susceptor in the form of a plurality of particles. The aerosol-forming substrate is a crimped tobacco sheet comprising tobacco material, fibers, binder, aerosol-former and the susceptor in the form of the plurality of particles.

First claim

The invention claimed is:

1. Inductively heatable tobacco product for aerosol-generation, the tobacco product comprises an aerosol-forming substrate containing a susceptor in the form of a plurality of particles, wherein the aerosol-forming substrate is a crimped tobacco sheet comprising tobacco material, fibers, binder, aerosol-former and the susceptor in the form of the plurality of particles, and wherein the susceptor has a Curie temperature between about 200 degrees Celsius and about 400 degrees Celsius.

2. Tobacco product according to claim 1 , wherein the tobacco product has a heat loss of at least 0.008 Joule per kilogram.

3. Tobacco product according to claim 2 , wherein the heat loss is more than 0.05 Joule per kilogram.

4. Tobacco product according to claim 1 , wherein sizes of the particles of the plurality of particles are in a range of about 5 micrometers to about 100 micrometers.

5. Tobacco product according to claim 1 , wherein the plurality of particles amounts to a range between about 4 weight percent and about 45 weight percent of the tobacco product.

6. Tobacco product according to claim 1 , wherein the plurality of particles is homogeneously distributed in the aerosol-forming substrate.

7. Tobacco product according to claim 1 , wherein the plurality of particles comprises a sintered material.

8. Tobacco product according to claim 1 , wherein the plurality of particles comprises an outer surface which is chemically inert.

9. Tobacco product according to claim 1 , wherein the plurality of particles is made of ferrite.

10. Tobacco product according to claim 1 , wherein the tobacco material is homogenized tobacco material and the aerosol former comprises glycerin.

11. Tobacco product according to claim 1 , wherein the crimped tobacco sheet has a thickness in a range of between about 0.5 millimeter and about 2 millimeters.

12. Tobacco product according to claim 1 , having the form of a rod with a rod diameter in the range between about 3 millimeters to about 9 millimeters, and with a rod length in the range between about 2 millimeters to about 20 millimeters.

13. Tobacco material containing unit comprising a tobacco product according to claim 1 and a filter, wherein tobacco product and filter are aligned in an endwise manner and are wrapped with a sheet material for fixing the filter and the tobacco product in the tobacco material containing unit.

14. Tobacco product according to claim 2 , wherein the heat loss is more than 0.1 Joule per kilogram.

15. Tobacco product according to claim 1 , wherein sizes of the particles of the plurality of particles are in a range of about 10 micrometers to about 80 micrometers.

16. Tobacco product according to claim 4 , wherein the plurality of particles is made of ferrite.

17. Tobacco product according to claim 5 , wherein the plurality of particles is made of ferrite.

18. Tobacco product according to claim 6 , wherein the plurality of particles is made of ferrite.

19. Tobacco product according to claim 9 , wherein the tobacco material is homogenized tobacco material and the aerosol former comprises glycerin.
