Lead-cadmium fluorogermanate glasses and transparent glassceramics. Spectroscopy and structure
(2006-12-01)
In Lead-cadmium fluorogermanate glasses (PbF2-CdF 2-PbGeO3) the addition of metal fluorides to the base PbGeO3 glass leads to a decrease of the glass transition temperature (Tg) and to an enhancement of the ionic conductivity ...
Bioactive glass and glass-ceramic orbital implants
(Wiley-Blackwell, 2019-09-01)
This review focuses on the applications of bioactive glasses and glass-ceramics in the field of orbital implants for ocular surgery. This use is relatively novel and less popular compared to the applications in orthopedics ...
Lead-cadmium oxyfluoride glasses and glass-ceramics
(Natl Inst Optoelectronics, 2002-09-01)
Glasses and glass-ceramics have been obtained in oxyfluoride systems involving lead and cadmium fluorides and one of the well-known glass former oxides SiO2, B2O3 and TeO2. Vitreous domains were established and a wide range ...

Influence of glass forming histories on the structural and thermal properties of tellurite glasses
(Soc Glass Technology, 2009-10-01)
Tellurite 20Li(2)O-80TeO(2) glasses were prepared with identical nominal composition but with different glass forming histories. Differential scanning calorimetry and x-ray diffraction techniques were used to study the ...
Innovating transparent glass ceramics based on Ga2S3-GeS2-CsCl
(Natl Inst Optoelectronics, 2009-09-01)
In this paper, we describe the preparation of glass ceramics in the Ga2S3 - GeS2 - CsCl system Visible and infrared transmitting glass ceramics were reproducibly obtained by appropriated heat treatment of the base glass ...
