一种高应变点硅酸盐玻璃及其应用
摘要：
本发明属于玻璃技术领域，特别涉及一种高应变点硅酸盐玻璃及其应用。所述高应变点硅酸盐玻璃，以氧化物质量百分比计，玻璃组成如下：56～70%SiO2，4.0～12.0%Al2O3，4.0～12.0%CaO，2.0～7.0%MgO，0～5.0%SrO，0～5.0%BaO，3.0～14.0%Na2O，0～7.0%K2O，1.5～6.0%ZrO2，0～1.0%TiO2，0～1.0%CeO2。本发明提供了一种应变点在560℃以上的玻璃，硬度高，适用于CIGS薄膜电池基板，同时适合化学钢化后作为中高档的触摸屏盖板玻璃。
摘要（英）：

The invention belongs to the technical field of glass, and in particular relates to silicate glass with high strain point and application thereof. According to mass percent of oxide, the silicate glass with the high strain point comprises the following components: 56-70 percent of SiO2, 4.0-12.0 percent of Al2O3, 4.0-12.0 percent of CaO, 2.0-7.0 percent of MgO, 0-5.0 percent of SrO, 0-5.0 percent of BaO, 3.0-14.0 percent of Na2O, 0-7.0 percent of K2O, 1.5-6.0 percent of ZrO2, 0-1.0 percent of TiO2 and 0-1.0 percent of CeO2. The glass with the stain point being over 560 DEG C is high in hardness, is suitable for a CIGS (Copper Indium Gallium Selenide) film battery substrate, and is suitable to be used as a cover plate glass of medium and high-grade touch screens after chemical tempering.
