Optical, Structural, Radiation shielding, and Mechanical properties for borosilicate glass and glass ceramics doped with Gd2O3

An extensive assessment of the impacts of BaO on the mechanical and gamma-ray attenuation properties of lead borosilicate glass

“…It can be noted in four bands. A small band is located at 550 and 560 cm −1 , which is related to the O–Si–O bending vibration mode 35 , while the band appearance at 690 and 703 cm −1 can be assigned to bending vibration B–O–B 46 . The large band centered at 906 to 971 cm −1 and 1039 to 1076 cm −1 can correspond to the B–O stretching of the tetrahedral BO 4 unit 48 The last band at high wavenumbers from 1388 to 1453 cm −1 and 1202 and 1247 cm −1 is associated with B–O stretching of trigonal BO 3 47 .…”

“…Many studies have explored borosilicate glass, especially in the radiation shielding field 31 – 35 . Cheewasukhanont et al 31 studied the impact of particle size on radiation shielding properties for the (55-x)SiO 2 –xBi 2 O 3 –20B 2 O 3 –10CaO–15Na 2 O glass system where x = 0, 5, 10, 15, 20 and 25 mol%.…”

“…Adding Bi 2 O 3 instead of SiO 2 increased the radiation shielding ability of the glass system. Mhareb 35 explored the structural, mechanical, optical, and radiation shielding properties for 10SiO 2 –10TiO 2 –30SrO–(49.5-x)B 2 O 3 –xGd 2 O 3 glass and glass ceramics where x = 0.5, 1, 1.5, and 2 mol%. Adding Gd 2 O 3 led to a slight variation in mechanical and optical properties.…”
