摘要 |
The present invention provide a fluorophosphate glass comprising 3 to 25 cation % of P5+, more than 30 cation % and 40 cation % or less of Al3+, 0.5 to 20 cation % of Li+ and 65 anion % or more of F- as glass ingredients, and having a liquid phase temperature of 700° C. or less. The fluorophosphate glass of the present invention has ultra low dispersibility and stability, and is preferably used for glass materials for press molding, optical element blanks and optical elements. |
