SrO-Bi2O3-B2O3 (SBBO)
transparent glasses were fabricated via the conventional melt quenching
technique. X-ray diffraction (XRD) was carried out to confirm the
glassy nature. Differential scanning calorimetry (DSC) was utilized
to gain knowledge about the crystallization temperature, and following
that glass samples were heat-treated to achieve crystallinity. The
obtained values of the glass transition temperature (T
g), the onset of crystallization temperature (T
cr), and the peak crystallization (T
p) temperature are 408, 438, and 440 °C, respectively.
The glasses were heated at 440 °C for 30 min, 1 h, and 2 h to
form glass-ceramics. The SrBi2B2O7 phase was formed during 1 h of heat treatment of the glasses. Studies
of active vibration modes were done by Raman spectroscopy for SBBO
glass and glass-ceramic samples. Piezocatalysis experiments were carried
out for the removal of organic pollutants with Methylene Blue (MB)
dye as a model dye, and the obtained maximum dye degradation was 51%
with a kinetic rate of 0.002 min–1 under 240 min
of ultrasonication. Experiments were repeated for 5 cycles to confirm
the repeatability, and different dyes were used for degradation to
confirm the reliability of the prepared glass-ceramic sample. Furthermore, Vigna radiata seeds were used to study the byproduct of
dye that had been degraded for the assessment of phytotoxicity.
