Research Abstract

The glass on the system of La_2O_3-TiO2 was prepared by containerless processing. The thermal stability and refractive indices of these glasses were investigated. It was found that these glasses had high refractive indices over 2. 29 and high glass transition temperatures. The high refractive index of these glasses was due to their large oxygen packing densities and significant electronic polarizabilities of oxygen ions. The substitution of Al_2O_3 and ZrO_2 was effective for the refractive indices and wavelength dispersions.
