Synthesis of highly refractive glasses was investigated. For the synthesis of the experimental glasses the phase diagram of the system Na/sub 2/O-- BaO--SiO/sub 2/ was taken, into which an increasing quantity of zirconium dioxide was introduced instead of SiO/sub 2/. The maximum content of ZrO/sub 2/ is 24%. The light refraction of the glasses increases with the increase of the zirconium oxide and barium oxide content. The crystallizability of the glasses was investigated, and it was found that those containing 8 to 16% zirconium dioxide are the most resistant to crystallization. Laboratory experiments were carried out with the addition of CaO and K/sub 2/O. Glass properties such as crystallizability, refractive index, chemical stability, softening temperature, and thermal expansion were investigated. (TCO)
