ることを目的とする。Conventionally, perfume such as perfume is soaked in cloth, cotton, or the like in order to maintain the fragrance for a predetermined period of time. However, there has been a problem that the fragrance causes the skin to become rough due to contact with the stains or damage of the cloth or the skin. In addition, a method of mixing a fragrance with a volatile solid material is used for a fragrance or the like. However, a special container is required, and there is a problem that the skin becomes rough when touching the skin. Furthermore, plastics are also made to contain fragrances. However, there are problems such as low aromaticity, restrictions on the types of fragrances contained, and the plastic itself being susceptible to environmental changes. There has been a demand for the development of a stable aromatic material that can maintain the aromaticity and does not cause harm to the human body or the like. The present invention has been made to meet the above-mentioned demands, and an object of the present invention is to provide an aromatic material in which the conventional disadvantages are improved.

体を得るため0.3t/cm2から2.0t/cm2が良い。Embodiments of the present invention will be described below. This carbon sintered body uses an organic carbon material having high strength as a starting material. The organic carbon material refers to a pulverized kneaded product using coke, carbon black, or graphite as an aggregate, using a pitch or a thermosetting resin as a binder, or a carbonaceous powder having self-sintering properties. The organic carbon material is formed into a desired shape by a normal forming method such as press forming or cold isostatic pressing. Molding pressure at this time, maintaining the green body shape, good 2.0 t / cm 2 from 0.3 t / cm 2 to obtain a molded article having low bulk specific gravity.

The firing temperature at this time is 800 at which the organic carbon material is polymerized, decomposed, and vaporized.
C or higher is good. This results in an open porosity of 3 vol% to 50 vol.

充填される。Next, the porous carbon sphere is degassed in a vacuum,
After filling the porous carbon spheres with the liquefied fragrance, the pressure is returned to the atmospheric pressure, and the fragrance is filled inside the porous material. It is better to use a high-pressure impregnating device and further apply a high pressure to further fill the fragrance. Thus, the porous portion of the carbon sphere is filled with a sufficient fragrance.

Was obtained. The compact was fired in a non-oxidizing atmosphere at 1000 ° C. for 1 hour to obtain a spherical sintered body. The open porosity of the obtained sintered body measured by the Archimedes method was 12 vol%. Next, the spherical porous sintered body was finished by polishing to obtain a glossy porous carbon sphere. After degassing the porous carbon spheres with a vacuum impregnating device, the porous carbon spheres were immersed in a liquid fragrance (ethyl vanillin manufactured by Shiono Perfume Co., Ltd.), and further impregnated with pressure by a high pressure impregnating device to obtain aromatic carbon spheres. The aromatic carbon spheres remained glossy and did not deteriorate even after being left in the air for three weeks or more, and maintained their aromatic character.
