Abstract: A process for the production of a substrate having antimicrobial properties is described. It comprises a step consisting of the déposition of a métal non-gelling layer comprising an inorganic antimicrobial agent, starting from a precursor, in métal, colloid, chelate or ion form on at least one of the surfaces of the glass substrate; and a step consisting of the diffusion of the agent into said at least one surface of the substrate by thermal treatment. Alternatively, the substrate may be coated with an underlayer or a topcoat and the diffusion occurs either in the underlayer or in the topcoat. Glass and metallic substrates having antimicrobial properties are also described. In particular, a substrate exhibiting a bactericidal activity measured in accordance with standard JIS Z 2801 of higher than log 2.

Abstract: The present invention relates to a glazing comprising: a substrate made of colored soda-lime glass composed of main glass-forming constituents and of coloring agents, which exhibits a selectivity (LT/ET) of at least 1.1, measured with Illuminant C for a glass thickness of 4 mm, and a coating deposited by pyrolysis on the colored glass substrate. The coating is a coating which provides the coated glazing with an increased selectivity with respect to the selectivity of the uncoated colored glass. Such a glazing is particularly used for vehicles of the motor vehicle or train type, or alternatively for buildings.

Abstract: A method of producing dealkalized sheet glass in which sheet glass is dealkalized in stages. The method includes dealkalizing sheet glass in a first stage by exposing the sheet glass to contact with a first dealkalizing medium including at least one acid gas for a period of at least 1 minute while the sheet glass is at a temperature above 400.degree. C.; and further dealkalizing the sheet glass in a subsequent stage by exposing the sheet glass after the first stage to contact with a second dealkalizing medium including at least one acid gas for a period of at least 3 minutes while the sheet glass is at a temperature which is at least 50.degree. C. below one of the temperature of the sheet glass during the first stage and the minimum temperature of the sheet glass during the first stage, and ranges between 400.degree. C. and 250.degree. C.

Abstract: Dealkalized sheet glass having a core region which is not dealkalized, having a pre-dealkalization bulk sodium ion concentration of at least 8%, calculated as weight percent sodium oxide in the sheet glass, which pre-dealkalization bulk sodium ion concentration continues to be maintained in the core region of the sheet glass, and having a surface which is dealkalized to a depth such that a sodium ion concentration gradient exists. The sodium ion depletion is maximum at the surface, the depth at which the sodium ion concentration is 90% of the pre-dealkalization bulk sodioum ion concentration is at least twice the depth at which the sodium ion concentration is 50% of the predealkalization bulk sodium ion concentration, and the sodium ion concentration at a depth of 50 nm is not more than 50% of the pre-dealkalization bulk sodium ion concentration. A long-lasting dealkalization is achieved because of a reduced tendancy to ionic migration due to the shape of said sodium ion concentration gradient.

Abstract: A glass article useful, for example, as a cathode ray tube screen, has a viewing light path which passes through at least one surface region over which the glass is matted by surface pits whereby unwanted specular reflection from that matted region is reduced. The light path also passes through a surface layer formed over a region of the glass so as to reduce the total light reflection from that region of the glass.

Abstract: Light transmitting glass has at least one surface area which is matted by surface pits. That surface area has a population of merging or contiguous surface pits, the pits being of such small area and profile that clearly legible typed characters of 10-pitch size are still clearly legible when viewed through such matted surface area when that surface is held at a distance of 10 cm from the said characters. At least one matted surface area may be occupied by a population of surface pits which are of such small size that a disk having a diameter of 10 micrometer cannot be placed thereon without overlapping at least two pits.
