Description

Fabrication of a (50)P${}_2$O${}_5$ - (50-$x$)BaO - ($x$)Bi${}_2$O${}_3$ glass systems where $x$ = 0, 2.5, 7.5, 12.5 and 17.5 mol% was carried out using a conventional melt-quenching method. The glass system has been investigated to see its potential use as radiation shielding material. The glass density was measured by using Archimedes principle. The micro-hardness of glasses was determined by ultrasonic velocities. The ultrasonic velocities were measured by the pulse echo technique, with a frequency of 4 MHz and at room temperature. FTIR spectroscopy has been used to study the structural properties of the prepared glass systems. The HVL (Half-Value Layer) show that this glass system is suitable as radiation shielding material and has some advantages comparing to the standard radiation shielding concrete.
