Abstract
A glass composition with high Young's modulus and specific modulus, wherein the glass composition includes the following components by weight percentage: 30-46% of SiO, 0-6% of BO, 10-30% of AlO, 4-20% of CaO, 2-15% of MgO, and 13-32% of YO. The glass composition uses common chemical raw materials. By reasonably arranging the contents of each component, the glass is good in heat resistance, chemical stability and press-molding devitrification resistance performance, low in high-temperature viscosity, convenient in bubble elimination, with specific modulus above 34 and Young's modulus above 100 GPa, and is suitable for hard disk substrate manufacturing, semiconductor sealing and other fields.
