    Experimental study of different oxides in B2O3–ZnO–BaO glass system for gamma-ray shielding by Mohamed Elsafi, M. I. Sayyed, Taha A. Hanafy

    Published 2025-01-01
    “…Abstract Glass system of 45B2O3–20ZnO–30BaO–5X, (where X represents CaO, MgO, Al2O3, TiO2, CuO and Fe2O3) in mole percentage was investigated for gamma ray radiation shielding experimentally. Six glass composites were fabricated and the density was measured experimentally and the BZBCa glass sample has the least density with a value of 3.932 g cm−3 and this is due to the presence of CaO in it, and the sample BZBFe has the highest density with a value of 4.031 g cm−3. …”
