To provide a stable aromatic material which maintains an aromatic property for a prescribed period and is harmless to the human body, etc., by packing liquid perfume into the open cells of a carbon sintered compact.
The pulverized matter of a kneaded mixture formed by using pitch and thermosetting resin as a binder and using coke, carbon back and graphite as aggregate or carbonaceous powder having self-sinterability is molded to a desired shape by an ordinary molding method, such as press molding or cold hydrostatic molding. Next, this molding is fired under a nonoxidizing atmosphere to polymerize, decompose and vaporize the organic matter contained therein, by which the porous carbon material having desired porosity is obtained. The firing temperature of this time is preferably, for example, ≥800°C which is the temperature, at which the polymerization, decomposition and vaporization of the organic carbon material occur. Next, the porous carbon ball is deaerated in vacuum and the perfume formed to a liquid form is filled into the porous carbon ball and thereafter the atmospheric pressure is restored to pack the perfume into the porous material. Further, the perfume is recommended to be further packed therein by applying a high pressure thereto using a high-pressure impregnation device. As a result, the sufficient perfume is packed into the porous carbon material.
