Mechanical, structural, and chemical properties of unmodified and iron-modified phosphate glass fibers based on natural phosphate and kaolin clay

Effect of Eu3+ and Tb3+ ions concentration on the mechanical, structural, and photoluminescence properties of phosphate glass fibers

“…All PGs samples were successfully transformed into continuous monofilaments fibers by a melt-draw spinning process. The spinning process reported here was carried out with the steps and precautions described in detail in our previous papers [20,21]. In this study, the winding speed was set at 538 rpm and the optimal spinning temperatures are 750 • C (temperature at the top) and 550 • C (temperature at the bottom).…”

“…Scanning electron microscope (SEM) image of the OJ 6 fiberglass sample was taken with ZEISS Supra 55VP scanning electron microscope. The mechanical properties of the PGFs were investigated by tensile tests using a tensile testing machine (model LUDWIC Mpk, made in Germany) [20,21], according to BS ISO 11566:1996 [22]. The values of the density (ρ) were measured by immersing the samples of PGFs according to the Archimedes technique (BS 10119) [21].…”

The values of the density (ρ) were measured by immersing the samples of PGFs according to the Archimedes technique (BS 10119) [21]. Then, the molar volume values (V m ) were calculated using the expression V m = M/ρ, where M is the molecular weight of PGFs.…”

Toward Atomistic Understanding of Iron Phosphate Glass: A First-Principles-Based Density Functional Theory Modeling and Study of Its Physical Properties

“…9 Iron phosphate glass optical fibers have also shown good mechanical properties, 10 and recently, ironcontaining phosphate glass fibers are also studied for slowrelease fertilizers. 11 For understanding its properties in various settings, atomistic models that can reproduce already observed experimental results are vital. These models can then be further utilized to access properties that are tough to obtain experimentally through simulations such as ab initio molecular dynamics (AIMD), classical molecular dynamics (CMD), and Monte Carlo methods.…”

“…Iron phosphate glass (IPG) has attracted a lot of research interest from glass scientists due to its superior properties that project it as a next generation material for vitrification of high-level radioactive waste from fast reactors. − Also recently, its application as an anode material in batteries was also investigated . Iron phosphate glass optical fibers have also shown good mechanical properties, and recently, iron-containing phosphate glass fibers are also studied for slow-release fertilizers . For understanding its properties in various settings, atomistic models that can reproduce already observed experimental results are vital.…”
