ビ材が求められていた。2. Description of the Related Art For example, as a method of antibacterial and antifungal treatment of a glaze, various kinds of silver or silver compounds have conventionally been added to the glaze. It has long been known that silver or a silver compound has an antibacterial and antifungal property called an oligodynamic effect. It is known that this effect is greater when silver is in an ionic state than in a metallic state. Antibacterial and antifungal properties can be obtained by adding silver and silver compounds to porcelain and enamel glazes. However, silver is expensive, and there has been a demand for an antibacterial and antifungal material which exhibits antibacterial and antifungal properties with a smaller amount of addition.

プを招くという問題点も有していた。In such prior art, a glaze component in which a glaze component is dispersed in water is often used in the manufacturing process of ceramics and enamel, but silver and silver compounds are used in the glaze. When added, the specific gravity of silver and the silver compound is much larger than the glaze component, so that there is a problem that sedimentation easily occurs in the glaze. When silver and silver compounds settle, naturally, the antibacterial properties of the products vary widely.
It became necessary to increase the amount of silver and silver compound added, which led to an increase in cost. In addition, when a silver compound is used, the glaze may be blackened or discolored or corrode other metals, which not only deteriorates the workability but also increases the cost because the precipitated metallic silver precipitates at this time. There was also a problem of inviting.

If it is lower than this, the reaction does not proceed, and if it is higher, volatilization of the component is recognized. The high temperature treatment causes the mixture to be either melted or not by other components. When melted, it is preferable to frit by quenching, and in this case, the subsequent pulverizing step becomes easy.

When the particle diameter is larger than this, sedimentation in the glaze is easy. The addition amount of the antibacterial and antifungal additive to the glaze is preferably 0.1 to 10% in consideration of workability. For this purpose, it is preferable that the silver content of the antibacterial and antifungal additive is 1% to 50%.

できるようになる。In the antibacterial and fungicidal additive of the present invention, firing or melting silver or a mixture of a silver compound and a silicate at a high temperature is performed by fusing or chemically bonding the silver or the silver compound and the silicate. It is to make it. By this treatment, silver and silver compounds and silicate are not separated in the glaze, and antibacterial and antifungal treatment can be performed with a small silver content.

ようになる。The specific gravity of silver and silver compounds is usually 6.0 or more, which is much larger than about 1.5 to 2.0, so that silver and silver compounds are selectively separated in the glaze. Although the sedimentation occurs, the antibacterial and fungicidal additive according to the present invention significantly improves the sedimentation by setting the specific gravity to 5.0 or less. In addition, when the pulverization is performed so that the average particle diameter is 10 μm or less, the particles are less likely to settle in the glaze.
In addition, in the antibacterial and fungicidal additive according to the present invention, the amount added to the glaze is 0.1 to 10%, and the silver content in the antibacterial and fungicidal additive is 1 to 50%, so that workability is improved. As a result, the total amount of silver added can be reduced.

食しにくいのである。Further, when silver and a silver compound according to the conventional method are used, the glaze is blackened and the workability is deteriorated. The conventional method blackens the glaze because silver itself is black because silver is used, and when other silver compounds are used, silver is reduced and precipitated by light and organic substances or metals. To do that. On the other hand, the antibacterial and antifungal additive of the present invention hardly causes blackening of the glaze. The reason why the additive is hard to be blackened is that silver is hardly eluted by the reaction with the silicate at a high temperature. In the conventional method, the elution of silver corrodes metals having a higher ionization tendency than silver. However, the antibacterial and antifungal additive of the present invention hardly corrodes metals other than silver due to little elution of silver.
