Study of optical glass with new property

摘要

Abstract: This study obtains many excellent properties of glass with high refractive index (n$-d$/ $EQ 1.7779,n$-F$/ $MIN n$-o$/ $EQ 0.01552) on the basis of V$- D$/ $EQ 50.1, acid resistance class 1 b and moist resistance class A as a result of designing new formulation and applying new technical and controlling structure and overcoming crystallization and updating rare earth optical glasses available. The group structural model of R$-m$/O$-n$/-R$-E(2)$/O$-3$/- Al$-2$/O$-3$/-SiO$-2$/-B$-2$/O$-3$/ multicomponent system is put forward for the first time as Fig. 1. The model is proved by x-ray diffraction, DTA, crystallization activation energy, IR spectrum, Raman spectrum, XPS spectrum, NMR, EXAFS, etc. A series of structural data is obtained. !13
