MAGNETO-OPTICAL GLASS Russian patent published in 2012 - IPC C03C3/68

Abstract RU 2452698 C2

FIELD: chemistry.

SUBSTANCE: invention relates to magneto-optical glass which contains terbium oxide, for use as devices operating on the Faraday effect. The obtained level of properties is achieved through composition of the magneto-optical glass which contains the following, mol %: Tb₂O₃ 20-31, SiO₂ 5-15, B₂O₃ 25-33, Al₂O₃ 12-15, GeO₂15-25.

EFFECT: invention enables synthesis of glass with high Verdet constant V with low absorption at operating wavelength and low susceptibility to crystallisation, which enables to obtain magneto-optical glass using conventional optical glassmaking techniques.
