Physical, Radiation Shielding and Crystallization Properties of Na2O-Bi2O3- MoO3-B2O3- SiO2-Fe2O3 Glasses A. F. Abd El-Rehim 1,2 & H. Y. Zahran 1,2 & I. S. Yahia 1,2 & Atif Mossad Ali 1,3 & Kh. S. Shaaban 4 Received: 17 September 2020 / Accepted: 5 November 2020 # Springer Nature B.V. 2020

Abstract The melt-quenching method has been used to fabricate 9Na2O-(30-x) Bi2O3- xMoO3-40B2O3- 20SiO2-1Fe2O3 glass system where x = (0 ≤ x ≤ 15 mol%). The XRD diffractometer procedure was used to check the status of these samples. Inter-ionic distance (Ri) between Mo–Mo, Polaron radius rp, and inter-nuclear distance ri reduce with the Mo content due to reduce of molar volume. The two-photon absorption coefficient TPA increase with the increase of MoO3 this increased connected to Eg. The values of ionicity Ib slightly increase and the covalency of these glasses reduce with a growth in MoO3 content. The XRD patterns of glass-ceramic show (Na2B4O7), B2Si2O5, Na2SiO3, Fe7BSi3O18, and LiBi (MoO4)2. The morphological of the glass-ceramic has been studied by SEM. FT-IR spectroscopic investigations of the glass-ceramic samples were applied to check the characteristic structure. Mass attenuation coefficient of the prepared samples decreased with the energy increase and with the addition of MoO3. Keywords Glasses . Ionicity . Glass-ceramic . Radiation shielding

1 Introduction Glass is an amorphous substance and has considerable potential in different fields. In many fields, glass materials are preferred to everyday use, such as bottles or windows, to advanced applications such as laser, medical, or military use. In the world today, transparency and durability are of interest as prominent glass properties. So, glass is a necessity for the present and the future. Silicate, borate, phosphate, germinate, arsenate, etc. are all different types of glass. Due to the transparent, and easy performance, the glass can be used as a protection substance [1–10]. Glasses of heavy metal oxide (HMO), includes about 50 mol of a heavy metal cation percent, (HMO) like MoO3, * Kh. S. Shaaban [email protected] 1

Fe2O3, Bi2O3, Ga2O3, and PbO [11–16]. These glasses have photon energy smaller than other glasses, and a higher refractive index. Therefore, the HMO glasses are transparent, promising materials for optoelectronics, fibers, sensors, optical instruments, good thermal, mechanical, and chemical stability, also offer superior optical and electrical properties [17–21]. In recent years, glasses beside MoO3 & Bi2O3 have been studied extensively due to its interesting features, high dielectric, good infrared transmission, and low melting temperatures
