Abstract
จัดให้มีแก้วซับสเตรทสหรับตัวกลางหน่วยเก็บข้อมูล ซึ่งมีความต้านทานอากาศที่ดีเยี่ยม แม้ว่าไม่มีการบำบัดเพิ่มเติม เช่น ใช้การบำบัดเสริมแรงทางเคมี และไวต่ำต่อปรากฎการทำให้ ขาวและซึ่งมีอุณหภูมิแทรนซิชันแก้วอย่างน้อยที่สุอ 680 ํC และมีความต้านทานกรดที่ดีเยี่ยม แก้วซับสเตรทสำหรับตัวกลางหน่วยเก็บข้อมูล ซึ่งประกอบด้วยที่แทนโดย % มอวล SiO2 จาก 47 ถึง 60%,Al2O3 จาก 8 ถึง20 %, MgO จาก 0 ถึง 8%, CaO จาก 0 ถึง 6%, SrO จาก 1 ถึง 18 % BaO จาก 0 ถึง 13%, TiO2 จาก 1 ถึง 6% จาก 1 ถึง 6%, Zro2 จาก 1 ถึง 5%, Na2O จาก 2 ถึง 8% และ K2O จาก 1 ถึง 15% และซึ่งมีอุณหภูมิแทรนซิชันแก้วอย่างน้อยที่สุด 680 ํC Provide a glass substrate for the storage medium. Which has excellent air resistance Although there is no additional treatment such as chemical reinforcement treatment, And low sensitivity to the appearance of making It is white and has a glass transition temperature of at least 680 ° C and has excellent acid resistance. Substrate glass for storage medium Which is represented by% moul, SiO2 from 47 to 60%, Al2O3 from 8 to 20%, MgO from 0 to 8%, CaO from 0 to 6%, SrO from 1 to 18% BaO from 0 to 13%, TiO2. From 1 to 6% from 1 to 6%, Zro2 from 1 to 5%, Na2O from 2 to 8% and K2O from 1 to 15% and where the glass transition temperature is at least 680 ° C.
