Abstract

See full text

The present invention discloses a glass with high refractive index for fiber optic imaging elements with medium-expansion and fabrication method therefor, the glass comprising the following components in percentage by weight: SiO2 5-9%, Al2O3 0-1%, B2O3 23-28%, CaO 0-3%, BaO 6-12%, La2O3 30-34%, Nb2O5 4-8%, Ta2O5 0-1%, Y2O3 0-1%, ZnO 4-9%, TiO2 4-8%, ZrO2 4-6%, SnO2 0-1%. The present invention further provides a fabrication method for the glass with a high refractive index, comprising: putting raw materials quartz sand, aluminum hydroxide, boric acid or boric anhydride, calcium carbonate, barium carbonate or barium nitrate, lanthanum oxide, niobium oxide, tantalum oxide, yttrium oxide, zinc oxide, titanium dioxide, zirconium oxide and stannic oxide, etc. into a platinum crucible according to the requirement of dosing, melting at a high temperature, cooling and fining, leaking and casting to form a glass rod, and then annealing, cooling and chilling the molded glass rod.
