Effect of Pb++/Sr++ Ratio on Physical, Structural, and Mechanical Properties of (Pb-Sr)TiO3 Borosilicate Glass Ceramics

Doping impacts of La2O3 on physical, structural, optical and radiation shielding properties of (30-x)BaCO3–30TiO2–40SiO2-xLa2O3 (0 ≤ x ≤ 6) glasses for optoelectronic applications

“…The XRD patterns of all the fabricated glasses, BTS0L, BTS2L, BTS4L, and BTS6L which were prepared in the BTSL glassy system are shown in the figure 2. XRD patterns showed a broad diffraction peak around 30 • in all the glass samples, which are confirming absence of long-range order structure, that peculiarities validated the amorphous or non-crystalline behaviour of all the prepared glasses [30,40,46].…”

“…From the obtained values (table 2) and figure3(a), it was clearly observed that the density increases on increasing the concentration of La 2 O 3 into the glasses. The probable reason of increment in ρ might be due to highest standard density of La 2 O 3 (6.51 g cm −3 ) as compare to the standard density of other components such as BaCO 3 (4.29 g cm −3 ), TiO 2 (4.23 g cm −3 ), and SiO 2 (2.65 g cm −3 ) or might be the highest molar mass of La 2 O 3 (325.81 g mol −1 ) among others component presented in the synthesized glasses or due to enhancement in NBO atoms[30,42,50]. Hence, the doping of La 2 O 3 inside the glassy system enhanced the compactness of the glassy networks.…”

“…To study the doping influence of La 2 O 3 on various physical, structural, and optical properties, a new chain of four bulk glasses were synthesized in the system (30-x)BaCO 3 −30TiO 2 −40SiO 2 -xLa 2 O 3 (x = 0, 2, 4, and 6 mole % of La 2 O 3 ), BTSL glasses via classic rapid melt-quenching technique respectively [26,27,30]. First of all, for the synthesis of 30 g glass batches, the appropriate quantities of AR grade raw materials (powders) viz.…”

“…For the preparation of glasses basically three major constituents are required; glass formers, glass modifiers, and glass intermediates. Glass former build up a structure inside a glassy matrix, for this purpose SiO 2 is found the best network former having good physical and optical properties because of high thermal stability, high clarity, high refractive index, and low dispersion [30]. Glass modifiers such as BaCO 3 enhance the structure formation, physical, optical, radiation shielding properties of the glasses [15,31].…”

“…It is well reported that the rare earth oxide, lanthanum oxide La 2 O 3 acts as a nucleating agent, and network modifier. It enhances the stability of glasses by establishing the ionic-bonds with the non-bridging oxygen (NBO) and also used to fabricate a ceramic superconductor in which the magnetic properties by inducing light [30,32]. La 2 O 3 also exhibits hexagonal type structure and is used in several research fields like electrical, optoelectronic devices [15,33,34].…”
