Abstract: A porous article is obtained by filling pores of at least one principal surface of a porous body which is formed of an inorganic material, with a mixture containing metal oxide particles and an alkaline silicate, in which the filled mixture is coated by a film containing a hydrated compound of zirconium and a silicate. According to this porous article, an effect of preventing surface contamination is superior, and alkali resistance and acid resistance are superior. In addition, a production treatment of the porous article can be performed at room temperature or at a relatively low temperature of 100° C. or lower. Therefore, the production cost can be significantly reduced.

Abstract: An excellent antibacterial property is afforded upon a metallic article by simple steps of coating a dispersion liquid or a solution of fine particles made of an antibacterial ingredient on the surface of the metallic article and pressing the resulting coated surface of the metallic article under a non-heated condition or rubbing the resulting coated surface of the metallic article. In addition, a conventional rolling step or the like can be used itself without any change in the above treatment, which is economically extremely advantageous. Furthermore, since the antibacterial metallic article according to the present invention is obtained under the non-heated condition, the antibacterial ingredient is not deteriorated. Further, since the antibacterial property is not lost through some abrasion, excellent antibacterial property can be exhibited over an extended time period. Further, there is no fear that surface characteristics of the metallic article, for example, a tone of color will change.
