Abstract: Substantially alkali free glasses are disclosed with can be used to produce substrates for flat panel display devices, e.g., active-matrix liquid crystal displays (AMLCDs). The glasses have high annealing temperatures and Young's modulus. Methods for producing substantially alkali free glasses using a downdraw process (e.g., a fusion process) are also disclosed.

Abstract: Methods of producing a glass article include melting a first glass composition and feeding a second glass composition into the melter. Both glass compositions include the same combination of components but at least one component has a concentration that is different in each. At least three glass articles may be drawn from the melter, including: a first glass article formed from the first glass composition; at least one intermediate glass article composed of neither the first nor the second glass composition; and a final glass article not composed of the first glass composition. The concentration of the at least one component in the intermediate glass article may be between the concentration in the first and second glass compositions. The first glass article and final glass article may have differing values for certain properties, and the intermediate glass article may have an intermediate set of values for the same properties.

Abstract: A method of strengthening an alkali aluminoborosilicate glass. A compressive layer extending from a surface of the glass to a depth of layer is formed by exchanging larger metal cations for smaller metal cations present in the glass. In a second step, metal cations in the glass are exchanged for larger metal cations to a second depth in the glass that is less than the depth of layer and increase the compressive stress of the compressive layer. Formation of the compressive layer and replacement of cations with larger cations can be achieved by a two-step ion exchange process. An alkali aluminoborosilicate glass having a compressive layer and a crack indentation threshold of at least 3000 gf is also provided.

Abstract translation: 一种强化碱铝硅玻璃的方法。 通过将存在于玻璃中的较小金属阳离子交换较大的金属阳离子，形成从玻璃表面延伸到层的深度的压缩层。 在第二步中，将玻璃中的金属阳离子交换为玻璃中较大金属阳离子至玻璃深度的第二深度，并增加压缩层的压缩应力。 压缩层的形成和用较大的阳离子取代阳离子可以通过两步离子交换工艺来实现。 还提供了具有至少3000gf的压缩层和裂纹压痕阈值的碱铝硼硅酸盐玻璃。

Abstract: An ion exchangeable glass that is free of lithium and comprising 0.1-10 mol % P2O5 and at least 5 mol % Al2O3. The presence of P2O5 enables the glass to be ion exchanged more quickly and to a greater depth than comparable glasses that do not contain P2O5.
