Problems solved by technology

[0004] However, when the inorganic titanium compound is coated or coated on the surface of the substrate, the durability of the coating film or the coating layer is insufficient, and there is a concern that the coating film or the coating layer is peeled off from the substrate.
For example, when a coating film is formed using the photocatalytic coating agent disclosed in Japanese Patent Laid-Open No. 2008-81712, there is a problem that the resin or organic binder remaining on the coating film is decomposed by ultraviolet rays or the like, or It is oxidized and reduced under the catalytic action of inorganic titanium compound, and as a result, the durability of the coating film tends to deteriorate over time
In addition, in order to fully exert the photocatalytic activity, the above-mentioned inorganic titanium com

Embodiment 1～21

[0207] Tables 1 to 3 show glass compositions, heat treatment (crystallization) conditions of Examples 1 to 21 of the present invention, and decomposition activity indices of these crystallized glasses. The crystallized glasses of Examples 1 to 21 all select and use oxides, hydroxides, carbonates, nitrates, fluorides, chlorides, metaphosphoric acid compounds, etc., which are generally used in the high temperature of glass, as the raw materials of each component. Purity of raw materials. Weigh and mix these raw materials according to the composition ratio of each example shown in Table 1 to Table 3, and then put them into a platinum crucible. According to the melting difficulty of the glass composition, use an electric furnace at a temperature of 1200 ° C to 1600 ° C Melt within the range of 1 to 24 hours, stir evenly for defoaming, etc. The molten glass is then cast into molds and cooled slowly to make glass. The obtained glass was ground, heated to the crystallization temper...

Abstract

The subject of the present invention aims to provide a photocatalysis functional material possessing excellent photocatalytic activity and durability. The present invention provides a crystallized glass possessing photocatalytic activity, and the components of the crystallized glass which are represented by being converted into oxides, comprise at least one of P2O5 component, TiO2 component and Nb2O5 component, and more than one component selected from ZnO component and RO component. The crystallized glass obtained by heating glass comprises a photocatalyst crystal, can be based on shapes, such as block shape, powder shape, fiber shape, sizing agent mixture, porous plastid, etc.

Description

technical field [0001] The present invention relates to crystallized glass, its production method and its utilization. Background technique [0002] A photocatalyst is a material that absorbs light to become a high-energy state, and uses this energy to chemically react reactive substances. As a photocatalyst, although metal ions, metal complexes, etc. are also used, titanium dioxide (TiO 2 ) and other semiconducting inorganic compounds are known to have high catalytic activity as photocatalysts, and are especially frequently used. Semiconductors generally do not conduct electricity, but when irradiated with light having an energy higher than the band gap energy, electrons move to the guide band to generate holes from which electrons have been removed, and the electrons and holes have a strong redox force. The oxidation-reduction power possessed by the photocatalyst decomposes and removes dirt, pollutants, malodorous components, and the like to perform purification. Since ...
