Abstract: The invention proposes an improvement in the characterization of solid materials, by making it easier to be implemented while obtaining reliable and accurate results. According to the method in accordance with the invention; a material to be characterized (M), in powdery form is placed in a well (4); while the material (M) is heated up by applying a predetermined power (P), a radiative thermal flux (F) emitted by the material is measured, and from the measurements relating to the radiative thermal flux (F), a characterization of the material (M) is inferred, related to the heat which this material loses by thermal conduction with the walls of the well (4).

Abstract: The aim of the invention is to improve the surface characterization of solid materials, facilitating the implementation thereof, while producing reliable and accurate results. The method of the invention comprises the following steps: obtaining a material (M) to be characterized, in powder form, and a gas mixture (G) containing a probe molecule (S) that can interact with the material, performing gas percolation through the material by flowing the gas mixture into the free spaces between the grains of the material, while leaving said grains in contact with each other, during the gas percolation through the material (M), measuring a radiative heat flux (F) emitted by the material, and at least one surface characteristic relating to the material (M) is deduced from the radiative heat flux (F) measurements.
