摘要：
A new system of glasses is composed essentially of 33-68 cation percent PbO, 2.5-27 cation percent CdO, 10-30 cation percent Fe2O3, and 4-28 cation percent Tl2O. The glasses are low-melting, have extremely high densities and refractive indices, and have excellent infrared transmission characteristics.
