The Influence of Boric Oxide on the Refractive Index and Dispersion of Soda–Boric Oxide–Silica Glasses

JSGT 1945 V29 T390-T396

New measurements of the refractive index, dispersion and v value have been undertaken in order to revise the data obtained in the Department in 1923. Three series of glasses have come under review having percentage compositions, respectively: (1) 80% (SiO₂+B₂O₃), 20% Na₂O. (2) 85% (SiO₂+B₂O₃), 15% Na₂O. (3) 90% (SiO₂+B₂O₃), 10% Na₂O.
