Abstract
In this study, structure, physical, optical characteristics as well as γ-ray protection capacity of boro-tellurite reinforced with ZrO2 glasses with general chemical formula (51-X)B2O3+20TeO2+19CaO+10Li2O + XZrO2 and substitution ratios of ZrO2 = 0, 1, 2, 3, and 5 mol% was investigated. All studied BTZO-X specimens were in non-crystalline state. Density (ρ) of BTZO-X increased from 2.80 g/cm3 to 3.11 g/cm3. Molar volume of BTZO-X declined from 28.85 cm3/mol to 26.89 cm3/mol. The absorption peak of BTZO-X samples shifted towards a red shift (longer wavelengths). The optical density (OD) enhanced, while the skin depth (ϕ) decreased as a function of photon energy. The mass-absorption (MAC) values accomplished the order; MAC (BTZO-5) > MAC (BTZO-3) > MAC (BTZO-2) > MAC (BTZO-1) > MAC (BTZO-0). Half-value layer and mean free path (MFP) verified the conditions; (BTZO-5)HVL,MFP < (BTZO-3)HVL,MFP < (BTZO-2)HVL,MFP < (BTZO-1)HVL,MFP < (BTZO-0)HVL,MFP. Results concluded that the suggested glass matrix can be used in optical and radiation shielding applications.
