| Περιγραφή: | The results of development of high-index glass for the products of ophthalmologic optics on the basis of the systems Li2O – RO – B2O3– SiO2and K2O – TiO2– SiO2are presented. It is shown that the formation of complexes [TiO4/2O] 2– K2 + in glass of the system K2O – TiO2– SiO2interferes with the formation of the chromophorecenters Fe 2+ – O – Ti 4+ and allows to receive colorless glass at amount of TiO2to 30 mol.%. The compositions of glass with a refractive index 1.65 and 1.70 at density no more than 2.91 g/cm 3 are developed. It allows to recommend them for the production of the facilitated lenses with a high optical force. |
