Radiation Shielding Properties Comparison of Pb-Based Silicate, Borate, and Phosphate Glass Matrices [PDF]

open access: yesScience and Technology of Nuclear Installations, 2014
Theoretical calculations of mass attenuation coefficients, partial interactions, atomic cross-section, and effective atomic numbers of PbO-based silicate, borate, and phosphate glass systems have been investigated at 662 keV. PbO-based silicate glass has

Degradable borate glass polyalkenoate cements [PDF]

open access: yesJournal of Materials Science: Materials in Medicine, 2014
Glass polyalkenoate cements (GPCs) containing aluminum-free borate glasses having the general composition Ag2O-Na2O-CaO-SrO-ZnO-TiO2-B2O3 were evaluated in this work. An initial screening study of sixteen compositions was used to identify regions of glass formation and cement compositions with promising rheological properties.

Hardness-Adapted Borate Glass as Wear Indicator

open access: yesChallenging Glass Conference Proceedings
Glass, in particular borate glass, is not only a very robust and hard material, but also offers good solubility for lanthanide ions. The lanthanide ions serve as luminescence centres in the glass system and emit a characteristic luminescence when ...

Bone bonding ability of some borate bio-glasses and their corresponding glass-ceramic derivatives [PDF]

open access: yesProcessing and Application of Ceramics, 2012
Ternary borate glasses from the system Na2O·CaO·B2O3 together with soda-lime-borate samples containing 5 wt.% of MgO, Al2O3, SiO2 or P2O5 were prepared. The obtained glasses were converted to their glass-ceramic derivatives by controlled heat treatment.

2pm/V in poled Bismuth-Zinc-Borate high index glass [PDF]

open access: yes, 2009
Thermal poling freezes an intense static electric field (Edc) in glass resulting in a permanent second-order nonlinearity via a rectification process: χ(2) = 3χ(3)Edc. The low third-order nonlinearity limits the χ(2) of silica glass to 0.7 pm/V.

Double-doped borate glass light guide with high luminance

open access: yes, 2022
The luminescence properties of Dy3+ and Tb3+ single- as well as Dy3+/Tb3+ double-doped barium borate glasses are investigated for their potential as light-converter.

Thermal behaviour of zircon/zirconia-added chemically durable borosilicate porous glass [PDF]

open access: yes, 2013
Macroporous alkali resistant glass has been developed by making additions of zirconia (ZrO2) and zircon (ZrSiO4) to the sodium borosilicate glass system SiO2–B2O3 Na2O. The glass was made using a traditional high temperature fusion process.

Structural investigations of borate incorporated germanium antimonate glasses

open access: yesResults in Chemistry, 2022
Germanium containing borate-based glass samples with the chemical formula (80–x)GeO2–10Sb2O3–10Na2O + xB2O3, where 0 ≤ x ≤ 40 mol% were fabricated for the generation of prominent infrared lasers.

The determination of mass attenuation coefficients through experimental and theoretical approaches using glass materials [PDF]

open access: yes, 2018
The mass attenuation coefficients, mu/rho of x(PbO or Bi2O3):(100-x)(SiO2 or B2O3) (x=30, 40, 50, 60, 70) glasses at 662 keV were measured according to the data available in the literature on borate glasses and silicate glasses.

Silica-Based and Borate-Based, Titania-Containing Bioactive Coatings Characterization: Critical Strain Energy Release Rate, Residual Stresses, Hardness, and Thermal Expansion

open access: yesJournal of Functional Biomaterials, 2016
Silica-based and borate-based glass series, with increasing amounts of TiO2 incorporated, are characterized in terms of their mechanical properties relevant to their use as metallic coating materials. It is observed that borate-based glasses exhibit CTE (
