Beschreibung
Zusammenfassung:The invention discloses a high-strength thick glass substrate which comprises the following raw materials in percentage by weight: 56-63 percent of SiO2, 6-8 percent of Al2O3, 2-6 percent of B2O3, 8-9percent of CaO, 3-5 percent of MgO, 13-15 percent of Na2O, 1-3 percent of K2O, 0-1 percent of Sb2O3 and 0.1-1 percent of a clarifying agent. The invention further discloses a preparation method of the high-strength thick glass substrate. The high-strength thick glass substrate prepared by the preparation method disclosed by the invention is high in mechanical and optical properties, good in melting effect and low in processing difficulty. 本发明公开了种高强度厚玻璃基片，该高强度厚玻璃基片包括以下重量百分比的组成原料：SiO：56％～63％；AlO：6％～8％；BO：2％～6％；CaO：8％～9％；MgO：3％～5％；NaO：13％～15％；KO：1％～3％；SbO：0％～1％；澄清剂：0.1％～1％。本发明还提供种上述高强度厚玻璃基片的制备方法。本发明制备得到的高强度厚玻璃基片力学性能和光学性能好、熔制效果好、加工难度小。
