| 總結: | This study investigate the structural and elastic properties glass system of
xCaO-10PbO-(90-x)B2O3 with composition (x = 20, 25, 30, 35 and 40) by
using melt-quenching method. The structural of the glass system is
determined by X-ray diffraction (XRD) and Fourier transform infrared
(FTIR) spectroscopy. FTIR analysis showed the functional group of BOB,
B04 and B03 in specific range. Meanwhile, for elastic properties are
determined by using pulse-echo method which also known as ultrasonic
measurement. Ultrasonic measurement used in order to obtain longitudinal
and shear velocities for each glass samples. By adding CaO content into
borate-lead glass system, it will increase the elastic moduli (Ke and CL) for x
≤ 35 mol% and later decreasing at x > 35 mol%. |
