Bismuth phosphate process

WebBismuth phosphate. The first successflil production method for the separation of Pu from U and its fission products was the bismuth phosphate process, based on the carrying of Pu by a precipitate of BiPO (126). That process has been superseded by Hquid-Hquid extraction (qv) and ion exchange (qv). WebApr 12, 2024 · Bismuth is an essential component in the creation of a radiation shielding material that can successfully replace lead. As compared to lead-silicate-based glass, silicate-based glass that has had bismuth oxide (Bi 2 O 3) added to it produces a material with a greater density and demonstrates improved shielding capabilities [7,8].
