The limits of the glass-forming region were determined. A series of new quaternary glasses ZrF 4 -BaF 2 -ThF 4 -MF x （x=1, 2, 3, andM=Li, Na, Ca, Sr, Zn, Cd, Al, Y, La, Gd） were obtained. The ultraviolet-visible and infrared transmission spectra, characteristic temperatures, refractive indices and densities of the fluoride glasses were measured. Glasses in quaternary system were more stable than these in the ternary system. These glasses are promising infrared transmission material, because of their good optical qualities and stability against devitrification. 钍 氟化物玻璃 红外透过 thorium fluoride glass infrared transmission 1990-04-01 2021-04-01 4
