New patent application published for: IRRADIATION-RESISTANT GLASS HAVING GAMMA-RAY SHIELDING AND NEUTRON PROTECTION FUNCTIONS AND PREPARATION METHOD THEREFOR

Irradiation-resistant glass having γ-ray shielding and neutron protection functions and a preparation method therefor. The glass material is prepared from the following components in percentage by mass: 25-45% of SiO.sub.2, 45-55% of PbO, 0.5-5% of Gd.sub.2O.sub.3, 0.5-1.5% of CeO.sub.2, 0.5-5% of Al.sub.2O.sub.3, 0-10% of Na.sub.2O, 2-10% of K.sub.2O, and 0-3% of an alkaline earth metal oxide selected from at least one of CaO and MgO, CaO and MgO being not both 0. The glass material has excellent gamma ray shielding performance, a good neutron protection function, and irradiation resistance, can be used for preparing a nuclear radiation shielding window, and has wide popularization and application prospects in complex environments in which gamma rays and neutron radiation are both present, e.g., nuclear power stations, nuclear power facilities, radiation diagnosis and treatment, and space detection.
