摘要:
Photochromic float glass and methods of making the same are provided. In especially preferred forms, the present invention is embodied in float glass having a non-photochromic glass substrate layer and a photochromic layer fused onto the substrate layer. During production, layers of the photochromic and non-photochromic glass are brought into contact with under conditions which fuse the layers one to another.
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 coated article includes a glass substrate that supports a coating such as a low-E (low emissivity) coating. In certain example embodiments, the glass substrate is formed of a soda-lime-silica based glass composition manufactured using a float process. In certain example embodiments, lithium oxide (e.g., LiO2) and/or potassium oxide (K2O) is used in the soda-lime-silica based glass substrate in order to reduce sodium migration and/or improve surface stability. Such coated articles are useful, for example and without limitation, in architectural, vehicular and/or residential glass window applications.
摘要:
A grey glass composition is suitable for architectural and/or vehicle window applications. The grey glass may achieve a combination of good visible transmission, a low SHGC, and desirable coloration. In certain example embodiments, the grey glass includes iron, erbium (Er), neodymium (Nd) and/or praseodymium (Pr) in the colorant portion of the glass.
摘要:
A grey glass composition employing as its colorant portion at least iron (Fe2O3/FeO) and erbium oxide (e.g., Er2O3), and also preferably selenium and cobalt. An exemplary colorant portion for use in a glass composition (with a soda lime silica or other suitable base glass) includes, by weight percentage: Total iron (expressed as Fe2O3): 0.1 to 0.6% erbium oxide (e.g., Er2O3): 0.3 to 1.5% selenium (Se): 0.0002 to 0.0010% cobalt oxide (e.g., Co3O4): 0.0005 to 0.0018% titanium oxide (e.g., TiO2): 0.0 to 1.0% boron oxide (e.g., B2O3): 0.0 to 2.0% The resulting glass may exhibit high visible transmittance (Lta), while at the same time low UV and IR transmittance.
摘要:
A glass composition employing as its colorant portion at least iron (total iron expressed as Fe2O3), erbium (e.g., Er2O3), and holmium (e.g., Ho2O3). The glass may be grey or otherwise colored in different embodiments. In certain example embodiments the colorant portion may include, by weight percentage: Ingredient wt. % total iron: 0.10-0.90% erbium oxide: 0.20-2.50% selenium: 0.0-0.0020% cobalt oxide: 0.0-0.0050% titanium oxide: 0.0-2.0% boron oxide: 0.0-2.0% holmium oxide: 0.10-1.60% thulium oxide: 0.0-2.0% ytterbium oxide: 0.0-3.0% lutetium oxide: 0.0-1.0%.
摘要:
A vacuum insulating glass (IG) unit and method of making the same. A plurality of fiber spacers (e.g. glass fibers) are provided between first and second opposing substrates in order to space the substrates from one another and maintain a low pressure space therebetween. The fiber spacers may be randomly distributed in a viewing area of the unit, or distributed in approximately uniform rows and/or columns in different embodiments of the invention. In certain embodiments, the fibers may be substantially transparent to certain wavelengths of visible light to render the IG unit more aesthetically pleasing.
摘要:
A high transmission and low iron glass is provided for use in a solar cell. The glass substrate may be patterned on at least one surface thereof. Antimony (Sb) is used in the glass to improve stability of the solar performance of the glass upon exposure to ultraviolet (UV) radiation and/or sunlight. The combination of low iron content, antimony, and/or the patterning of the glass substrate results in a substrate with high visible transmission and excellent light refracting characteristics.
摘要:
A grey glass composition employing in its colorant portion, in certain example embodiments, iron, cobalt, nickel, and at least one of erbium and titanium. The use of erbium and/or titanium has been found to improve coloration of the grey glass, and improve tunability of the same. In certain example embodiments, the ratio of cobalt oxide to nickel oxide is from 0.22 to 0.30 in order to achieve desired coloration in certain example embodiments.
摘要:
A glass composition including from 0.10 to 2.0% yttrium oxide (e.g., Y2O3) and employing in its colorant portion iron (total iron expressed as Fe2O3), erbium (e.g., Er2O3), and/or holmium (e.g., Ho2O3). In certain embodiments, the glass may be grey in color.
