    摘要: A soda-lime-silica based glass composition for manufacturing on a float line that has a faster refining rate due to the introduction of alkali earth oxides such as BaO, ZnO and/or SrO in the amount of from about 1-4% in total. These oxides replace part or all of the MgO in the base glass composition thereby decreasing the overall MgO content in the glass composition to about 2% or less. The glass can realize a lower viscosity at high temperatures so that refining of the melt may occur faster.

    摘要: A vacuum insulating glass (IG) unit and method of manufacturing the same. A peripheral or edge seal (11) of a vacuum IG unit is formed utilizing microwave energy (17) in order to enable tempered glass sheets (2, 3) of the IG unit to retain a significant portion of their original temper strength. In certain exemplary embodiments, the edge seal may be formed of glass frit or solder glass. In certain embodiments, at least a portion (12, 12a, 301) of the edge seal material may be deposited on one or both substrates prior to a thermal tempering process so that during tempering the edge seal material is permitted to diffuse into (i.e., bond to) the glass substrate(s) (2, 3). Optionally, additional edge seal material (303) may be added after tempering. The final edge seal (11) is preferably formed via microwave heating (17) of the edge seal material.

    摘要: The present invention provides a glass composition having a neutral gray color and a luminous (visible) transmittance within a range that allows the glass to be used in the forward vision areas of a vehicle. The base glass is a soda-lime-silica composition and iron, cobalt, selenium and/or nickel are added as colorants. In one particular embodiment of the invention which is essentially nickel-free, a neutral gray colored glass with a luminous transmittance (C.I.E. illuminant A) of 60% and higher at a thickness of 3.9 millimeters may be attained by using as colorants: 0.30 to 0.70 wt. % Fe.sub.2 O.sub.3, no greater than 0.21 wt. % FeO, 3-50 PPM CoO and 1-15 PPM Se, and preferably 0.32 to 0.65 wt. % Fe.sub.2 O.sub.3, 0.065 to 0.20 wt. % FeO, 5 to 40 PPM CoO and 1 to 9 PPM Se. In an alternate embodiment of the invention which includes nickel oxide as a colorant, a neutral gray colored glass with a luminous transmittance of 60% and higher at a thickness of 3.9 millimeters may be attained by using 0.15 to 0.65 wt. % Fe.sub.2 O.sub.3, no greater than 0.18 wt. % FeO, 15-55 PPM CoO, 0-5 PPM Se and 25-350 PPM NiO as colorants, and preferably 0.17 to 0.60 wt. % Fe.sub.2 O.sub.3, 0.04 to 0.16 wt. % FeO, 20 to 52 PPM CoO, 0 to 3 PPM Se and at least 50 PPM NiO.
