| Abstract: | Glass formation region of B_2O_3-La_2O_3Ta_2O_5-ZrO_2 and B_2O_3-La_2O_3-Nb_2O_5-ZrO_2 systems containing 20% B_2O_3(in mass)has been determined.Other oxides which can improve divitrification characteristics of the glass were then added respectively.A new type of ZLaF_4 optical glass with high refractive index and low dispersion has been developed.Its melting process and divitrification characteristics were also discussed and its some other properties were also measured in the present paper. |
