NOVEL RARE-EARTH PHOSPHATE GLASSES AND A PROCESS FOR THE PREOARATION OF SAID GLASSES

机译:新型稀土磷酸盐玻璃及其制备方法

摘要

(La2O3)5-10(RxOy)5-10(Al2O3)5-10(P2O5)70-85 wherein RxOy reopresents any one lanthanide oxide selected from the group consisting of La2O3, CeO2,Pr6)11, Nd2O3, Eu2O3, Tb4O7, Ho2O3, Er2O3 and the value of x and y depends on the valency of the rare-earth ion used. This invention and its embodiments relate to these types of glasses; to the kind of process for their preparation; and to the special properties and characteristics of these glasses. Examples of the special properties and characteristics of the said glasses are; structures made up of continuous random networks; special optical transmission and absorption characteristics in the visible and ultraviolet wavelength ranges; good resistance to attack by moisture; and good mechanical strength.
