Abstract

The optical properties of the CaO-Al₂O₃-B₂O₃ glasses are reported in this paper. The variation of refractive index, dispersion, ultra-violet absorption and density with composition is in agreement with the dielectric properties results previously published. Inflections in the physical property curves are discussed in terms of formation of the non- bridging oxygens. Infrared spectroscopy suggests the presence of the boroxol groups up to 40 mol% CaO. The tetraborate groups gradually diminish on increasing the CaO concentration higher than 25 mol%.
