Patent number: 11440836Abstract: A glass composition with high Young's modulus and low density. The glass composition includes the following components by mole percentage: 52-70% of SiO2, 5-10% of B2O3, 5-15% of Al2O3, 8-20% of CaO and 5-18% of MgO. The glass composition uses common chemical raw materials. By reasonably designing the contents of each component, the glass composition has high Young's modulus, low density, good heat resistance and chemical stability, relatively low high-temperature viscosity, and low raw material cost. The glass composition is easy to eliminate stripes and bubbles during manufacturing, and is suitable for hard disk substrate manufacturing other fields that need high Young's modulus materials.Type: GrantFiled: April 10, 2019Date of Patent: September 13, 2022Assignee: CDGM GLASS CO., LTDInventors: Lulu Mao, Wei Sun, Bo Kuang
