PROBLEM TO BE SOLVED: To improve handleability and malodorous substance adsorbing performance, to easily remove adsorbed malodorous substances and to enable use over a long period of time by using a composition in a sintered hollow body, which consists of one or more carbides, porous microcapsules housing titanium dioxide and a resin for shape retainment. SOLUTION: A powdery carbide, porous microcapsules housing titanium dioxide and a novolak type phenolic resin containing a curing catalyst are blended in a prescribed ratio and dispersed in water. The resultant pasty mixture is extrusion-molded into a honeycomb hollow body whose hollow part consists of many cells 2 formed by a latticed wall 1 and the hollow body is dried and sintered in an atmosphere of nitrogen to obtain the objective water purifying tool A for rice cooking. This water purifying tool efficiently adsorbs malodorous substances contained in water in a short time. The adsorbing performance of the fine carbide powder can be always effectively utilized by putting the water purifying tool under sunlight, a fluorescent lamp or the like after use and the tool can be repeatedly used over a long time. |
