    摘要: Abrasion resistant glass, which consists essentially of the following components: ______________________________________ SiO.sub.2 75.5 to 85.5 (wt %), RO 1 to 8 (wt %), R'.sub.2 O 10 to 23.5 (wt %), RO + R'.sub.2 O 11 to 24.5 (wt %), Al.sub.2 O.sub.3 0 to 5 (wt %), ______________________________________ RO/R'.sub.2 O (weight ratio) at most 0.5, provided that R is at least one member selected from Mg and Ca, and R' is at least one member selected from Li, Na and K, and of which the density measured at room temperature is at most 2.41 g/cc.
