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 ...
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 ...

Lead-germanate glasses and fibers: A practical alternative to tellurite for nonlinear fiber applications
(2013-09-20)
We report on the fabrication of novel lead-germanate glasses and fibers. We have characterized these glasses in terms of their thermal properties, Raman spectra and refractive indices (both linear and nonlinear) and present ...
Viscosity of fluoroindate glasses
(1998-12-01)
The viscosity of two fluoroindate glasses was measured as a function of temperature in the range of 310 °C - 362 °C. In such interval, the viscosity values were found to be similar to those reported for fluorozirconate ...
Thermal properties of fluoride glasses and their gel precursors
(Kluwer Academic Publ, 2004-01-01)
Xerogels were prepared from zirconium, barium, aluminum, lanthanum and lithium acetates, corresponding to a Li containing ZBLA composition. The study of their thermal properties (DSC, TG/DTG, FT-IR) showed that they might ...

Inversion in the temperature coefficient of the optical path length close to the glass transition temperature in tellurite glasses
(American Institute of Physics (AIP), 2009-06-22)
In this study, thermal lens spectrometry was applied to determine the thermo-optical properties of fragile tellurite glasses as a function of temperature, close to the glass transition region. The results showed an inversion ...
