SOLUTION: The sealing material excellent in antibacterial/antifungal properties and color fastness is obtained by adding a soluble glass to the sealing material. The soluble glass essentially comprises zinc, which has an antibacterial/antifungal effect, and preferably has a composition comprising 25-70 wt.% ZnO, 20-70 wt.% B
2 O
3 and 1-25 wt.% at least one chosen from the group consisting of Na
2 O, K
2 O, Li
2 O, CaO, MgO and BaO. The antibacterial/antifungal property can be improved by further adding 0-5 wt.% Ag
2 O.

Abstract: PROBLEM TO BE SOLVED: To provide a glass composition having antibacterial functions, from which the dissolution of the components of a glass network can be suppressed to be minimum and only a modifying oxide contained can be selectively eluted, and which exhibits excellent durability.
SOLUTION: The glass composition having the antibacterial functions contains the modifying oxide component for eluting metal ions. The glass composition contains, as the components of the network, Si, B, P and Al, and has the network of a Si component or the network comprising the Si component and one or more kinds of B, P and Al components. The Si component is contained in an amount of ≥50 wt.% expressed in terms of its oxide.

Abstract: PROBLEM TO BE SOLVED: To provide a method for easily manufacturing high-quality foamed glass utilizing a continuous melting furnace.
SOLUTION: The method for manufacturing the foamed glass with the continuous melting furnace comprises: a step of charging into molten glass in a forehearth 1 a foaming agent which is granulated into particles with particle sizes of 3-10mm and a specific gravity of 2.0 or more; and a next step of homogeneously mixing glass material with the foaming agent by stirring them with a stirrer 7 so as to generate bubbles throughout the glass material. Furthermore, it is preferable that the whole surface of the particles of the granulated foaming agent 10 is adhesively coated with hardly soluble glass fine powders 11 so that foaming start time is adjusted to be delayed so as to start foaming around the bottom of the glass material.

Abstract: PROBLEM TO BE SOLVED: To enhance the planeness of a glass substrate and to minimize cracks in the substrate by lapping the substrate, then, forming a tempered layer of a specified thickness or more by chemical tempering, polishing and removing the tempered layer on the principal surface by a specified dimension of more by polishing and leaving the tempered layer in a specified dimension or more.
SOLUTION: A glass substrate is lapped to form a doughnut-shaped substrate. Then, the substrate is immersed in a mixed molten salt consisting of potassium nitrate and sodium nitrate at 380°C for 1 hr so that a tempered layer of ≥20 μm thickness is formed by chemical tempering. The raggedness caused on the glass substrate by the chemical tempering is perfectly removed by polishing. Since the tempered layer is formed thick on the surface of the glass, the glass substrate is hardly broken by polishing. The tempered layer on the principal surface is required to be polished and removed by ≥10 μm thickness but it is required to be left in ≥10 μm thickness in order to maintain the strength.
