Abstract:
A glass composition comprising: (A) TeO2 (50-95 mol %); (B) B2O3 (1-33 mol %); (C) ZnO (1-37 mol %); (D) Bi2O3 (1-18 mol %); (E) P2O5 (0-15 mol %); (F) R2O (0-13 mol %), where R represents at least one element selected from the group consisting of Li, Na, and K; (G) MO (0-13 mol %), where M represents at least one element selected from the group consisting of Mg, Ca, Sr, and Ba; (H) TiO2 (0-13 mol %); (I) Nb2O5 (0-10 mol %); (J) Ta2O5 (0-13 mol %); (K) L2O3 (0-11 mol %), where L represents at least one element selected from the group consisting of yttrium and lanthanoids; and (L) the total amount of P2O5, R2O, MO, TiO2, Nb2O5, Ta2O5, and L2O3 described in (E) to (K), respectively, is 0-15 mol %.
