Glass Composition for Lamp and Lamp Manufactured From the Same |
摘要 |
A glass composition for lamps includes: SiO<SUB>2 </SUB>(silicon dioxide) as a main component; Na<SUB>2</SUB>O (sodium oxide) in the range of 12 to 17 wt. %; MgO (magnesium oxide) in the range of 2.5 to 4 wt. %; and CaO (calcium oxide) in the rage of 5.3 to 7.3 wt. %, wherein the total content of MgO and CaO is in the range of 8 to 11 wt. %. Thereby, lamps can be manufactured at relatively low costs that exhibit superiority in fracture resistance, workability, erosion resistance with respect to the inner surface of a furnace, and suppressing the elution of alkali component.
