Ceramic crucibles: a new alternative for melting of PbO–BiO1.5–GaO1.5 glasses

PbO–Bi2O3–Ga2O3 glasses present interesting properties such as good transmission in the mid-infrared region, high magnetic Verdet constant and non-linear properties. The processing of these heavy-metal-oxide (HMO) glasses is limited by the high corrosive nature of the melt, even in relation to noble...
