Aluminosilicate glass containing Y2O3 concentrate and ZrO2 |
| 摘要 |
A process for preparing aluminosilicate glass comprising from 30 to 60 molar % of SiO2, from 20 to 35 molar % of Al2O3 and from 10 to 30 molar % of a total of rare earth oxides composed mainly of Y2O3, wherein an yttrium concentrate is used as the rare earth oxides composed mainly of Y2O3, and ZrO2 not in excess of 8 molar % to improve alkali resistance.
