A study on crystallization property of optical glasses in RO-ZrO/sub 2/-La/sub 2/O/sub 3/-SiO/sub 2/-B/sub 2/O/sub 3/ system
Description
Rare earth optical glasses have the properties of high refractive index and low dispersion, but the glasses crystalize easily. This problem has not been solved very well though some research work about composition and technique has been done at home and abroad. It is impossible to solve the problem only by changing the composition and technique. Thus, the structural state of glass must be adjusted. Unstable, isolated small complex ions are formed in the system. These complex ions must be filled in the gaps formed by strong complex anions group. Rare earth optical glass systems are ordinarily borate system, because B/sub 2/O/sub 3/ has high field intensity which is 13/(0.023)/sup 2/=5671.28. In order to increase the stability of system, BaO and CaO that can provide dissociative oxygen are added to the system
