Disclosed is a method of manufacturing a dishwasher including: forming a first layer containing zirconium oxide and silicon oxide on a surface of the inner wall at a heat treatment of 200&#xb0; C. or higher; forming a second layer containing an oxoacid on a surface of the first layer at a heat treatment temperature lower than the heat treatment temperature of the first layer; and obtaining a thin-film layer containing zirconium oxide and silicon oxide on the surface of the inner wall and having a contact angle of water of 20&#xb0; or less on the surface, after removing the second layer by using a washing method, in which the first layer contains the zirconium oxide in an amount of 80 mass % or more in terms of oxide and the silicon oxide in an amount of 1-20 mass % in terms of oxide.

Method of manufacturing dishwasher

The cooking device of the present invention comprises a base material and a thin film that is formed on a surface of this base material, wherein said thin film contains silicon (Si), zirconium (Zr) and oxygen (O), and is such that when said silicon (Si) and said zirconium (Zr) are respectively converted to silicon oxide (SiO) and zirconium oxide (ZrO), the weight percent of said silicon oxide (SiO) relative to the total amount of said zirconium oxide (ZrO) and said silicon oxide (SiO) is 50 weight % or less.

An antibacterial, antifungal or antialgal article includes an antibacterial, antifungal or antialgal component, for example, silver and copper, an alloy thereof or a compound thereof diffused from a surface into the inside of the surface portion of an article, for example, a metal, glass or ceramic article.

Antibacterial, antifungal or antialgal article and process for producing same

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.

Method of producing antimicrobial metal articles and antimicrobial metal articles produced by the method

The present invention provides an anti-bacterial and anti-fungal glaze composition for ceramic products formed by incorporating a silver-containing substance; and a fire resistant material and/or glass composition. The present invention can be used in the manufacture of ceramic products requiring sanitary properties such as tile, sanitary earthenware, commodes, bath tubs and the like, and according to the present invention, anti-bacterial and anti-fungal properties can be effectively exhibited therein. In particular, the present invention can be used in sink basins, tile, commodes, bath tubs, and the like of hospitals, hotels and public facilities.

A sintered alumina article having an excellent flexural strength comprises numerous sintered plate crystalline corundum particles each having cleavage surface planes and accumulated on and bonded to each other in a manner such that the cleavage surface planes of the accumulated plate crystalline particles are substantially in parallel to each other and can be produced by forming the plate crystalline corundum particles into a predetermined shape so that the plate crystalline particles are accumulated in the above-mentioned manner; and by sintering the resultant precursory article at 1500.degree. C. or more under the ambient atmospheric pressure.
