The present disclosure relates to a glass composition having a low thermal expansion coefficient, specifically, a glass composition comprising about 55 to less than 64 weight percent of silicon oxide, about 15 to about 30 weight percent of aluminum oxide, about 5 to about 15 weight percent of magnesium oxide, about 3 to about 10 weight percent boron oxide, about 0 to about 11 weight percent calcium oxide, and about 0 to about 2 weight percent of alkali oxide, the remainder being trace compounds of less than about 1 weight percent, is provided. Glass fibers and composite articles formed therefrom are also provided.

Glass composition with low coefficient of thermal expansion, and glass fiber produced from same

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.

Glass composition for improved refining and method

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.

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.

Grey glass composition

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.

Grey glass composition including erbium, neodymium and/or praseodymium

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., LiO) and/or potassium oxide (KO) 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.

Coated article including soda-lime-silica glass substrate with lithium and/or potassium to reduce sodium migration and/or improve surface stability and method of making same

An apparatus and method for bending and/or tempering glass substrate(s) are provided. The amount of near-IR radiation which reaches the glass to be bent and/or tempered is limited (e.g., via filtering or any other suitable technique). Thus, the IR radiation (used for heating the glass) which reaches the glass to be bent and/or tempered includes mostly mid-IR and/or far-IR radiation, and not much near-IR. In such a manner, coating(s) provided on the glass can be protected and kept at lower temperatures so as to be less likely to be damaged during the bending and/or tempering process. Heating efficiency can be improved. A ceramic (e.g., aluminosilicate) filter or baffle may be used in certain embodiments in order to reduce the amount of mid-IR and/or far-IR radiation reaching the glass to be tempered and/or bent.

Apparatus and method for bending and/or tempering glass

This invention relates to a method of making a laminated window such as a vehicle windshield. At least one of the two glass substrates of the window is ion beam milled prior to heat treatment and lamination. As a result, defects in the resulting window and/or haze may be reduced.

Method of manufacturing windshield using ion beam milling of glass substrate(s)

This invention relates to a method of making a window (e.g., vehicle windshield, architectural window, etc.), and the resulting window product. At least one glass substrate of the window is ion beam treated and/or milled prior to application of a coating (e.g., sputter coated coating) over the treated/milled substrate surface and/or prior to heat treatment. As a result, defects in the resulting window and/or haze may be reduced. The ion beam used in certain embodiments may be diffused. In certain embodiments, the ion beam treating and/or milling is carried out using a fluorine (F) inclusive gas(es) and/or argon/oxygen gas(es) at the ion source(s). In certain optional embodiments, F may be subimplanted into to treated/milled glass surface for the purpose of reducing Na migration to the glass surface during heat treatment or thereafter, thereby enabling corrosion and/or stains to be reduced for long periods of time.
