    • Glasses are disclosed which can be used to produce substrates for flat panel display devices, e.g., active matrix liquid crystal displays (AMLCDs). The glasses have MgO concentrations in the range from 1.0 mole percent to 3.0 mole percent and Σ[RO]/[Al 2 O 3 ] ratios greater than or equal to 1.00, where [Al 2 O 3 ] is the mole percent of Al 2 O 3 and Σ[RO] equals the sum of the mole percents of MgO, CaO, SrO, and BaO. These compositional characteristics have been found to improve the melting properties of batch materials used to produce the glass, which, in turn, allows the glasses to be fined (refined) with more environmentally friendly fining agents, e.g., tin as opposed to arsenic and/or antimony.
    • 公开了可用于制造平板显示装置的基板的玻璃,例如有源矩阵液晶显示器(AMLCD)。 玻璃具有在1.0摩尔%至3.0摩尔%范围内的MgO浓度和大于或等于1.00的S [RO] / [Al 2 O 3 O 3]比例, 其中[Al 2 O 3]是Al 2 O 3 3的摩尔百分数,S [RO]等于 MgO,CaO,SrO和BaO的摩尔百分数之和。 已经发现这些组合特征提高了用于生产玻璃的批料的熔化性能,这又使玻璃用更环保的澄清剂(例如锡)与砷和/ 或锑。
