【Abstract】 The formation and properties of fluoride glasses in the system ZrF₄-BaF₂-ThF₄ were examined. The limits of the glass-forming region were determined. A series of new quaternary glasses ZrF₄-BaF₂-ThF₄-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.更多还原
