GLASS Russian patent published in 2016 - IPC C03C3/95

Abstract RU 2574230 C1

FIELD: chemistry.

SUBSTANCE: glass has the following composition, wt %: SiO₂- 62.0÷71.0; B₂O₃- 3.28÷10.0; Al₂O₃- 1.0÷4.0; Na₂O - 5.0÷14.8; CaO - 2.0÷6.0; MgO - 1.0÷8.0; ZnO - 0.5÷8.0; S - 0.1÷1.2; CeO₂- 0.1÷3.0; Se - 0.02÷0.8. Glass for microspheres is synthesised by common technology. Selenium is introduced through sodium selenate Na₂SeO₃. Cerium is introduced into glass structure through oxide. SO₃ is introduced into glass-mass by means of sodium sulphates.

EFFECT: increase of glass light-transparency in visible area of spectrum and reduction of density of hollow microspheres, produced from claimed glass.
