High tantalum oxide content in Eu3+-doped phosphate glass and glass-ceramics for photonic applications
(2020-11-25)
Transparent Eu3+-doped tantalum phosphate glass-ceramics containing Na2Ta8O21 nanocrystals were successfully obtained by a two-step heat treatment. Structural analyses were performed using X-ray diffraction, Transmission ...
Fatigue failure load of two resin-bonded zirconia-reinforced lithium silicate glass-ceramics: Effect of ceramic thickness
(2018-06-01)
Objectives: To evaluate the effect of ceramic thickness on the fatigue failure load of two zirconia-reinforced lithium silicate (ZLS) glass-ceramics, adhesively cemented to a dentin analogue material. Methods: Disc-shaped ...
Ceramic Crucible Corrosion by Heavy Metal Oxide Glasses, Part I: Phenomenological Study
(2003-07-01)
Heavy metal oxide (HMO) glasses have received special attention due to their optical, electrical and magnetic properties. The problem with these glasses is their corrosive nature. In this work, three ceramic crucibles (Al ...

Lead-cadmium oxyfluoride glasses and glass-ceramics
(Natl Inst Optoelectronics, 2014)
Effects of incorporating natural minerals on production and bioactivity of bioactive glass ceramics
(Inst Chemical Technology, 2016-05)
Two glass-ceramics composition were produced from natural minerals. Quartzes and feldspars were pre-selected on the basis of their purities studied by X-ray diffraction (XRD) and chemical analysis. Prepared compositions ...
Crystallization kinetics of glass prepared with foundry slag
(2021-07-01)
Iron foundry slag and hydrated lime were used in glass preparation by the melt-quenching method. The glass obtained was heat-treated using the thermal analysis technique. A crystallization kinetics study was carried out ...
Optical properties and energy-transfer frequency upconversion of Yb 3+-sensitized Ho3+- And Tb3+-doped lead-cadmium-germanate glass and glass ceramic
(2006-05-09)
In this report we investigate the optical properties and energy-transfer upconversion luminescence of Ho3+- and Tb3+/Yb 3+-codoped PbGeO3-PbF2-CdF2 glass-ceramic under infrared excitation. In Ho3+/Yb 3+-codoped sample, ...
