Structural, thermal, optical, and gamma rays attenuation properties of a developed potassium bismuth lanthanum borosilicate glass.

A host glass matrix composed of potassium bismuth borosilicate that has been reinforced with 2, 4, 8, and 16 mol% La 2 O 3 to act as a gamma-ray shield. Thermal, optical, and shielding qualities have been impacted by the penetration of La 2 O 3 into the suggested host glass, which fills the interstitial spaces. The density increases from 4.304 g/cm3 to 6.384 g/cm3 with an increase in La 2 O 3 while (V m) decrease. The glass under consideration demonstrated a high degree of thermal stability as the content of La 2 O 3 increased. When La3+ ions are added, the resulting glasses' optical transparency improves to above 77 %. The origin of these glasses is non-metallic. Gamma-ray attenuation of the glasses was developed with increasing amounts of La 2 O 3. The glass containing 16 mol% La 2 O 3 is a promising candidate for protective shields in various nuclear applications due to its high thermal stability, transparency, and effective capability to reduce gamma rays. • Potassium bismuth borosilicate glasses containing La 2 O 3 that were manufactured. • The density increases from 4.304 g/cm3 to 6.384 g/cm3 V m). • The glass containing 16 mol% La 2 O 3 is a promising candidate for protective shields.
