Systematic investigation on durability of glass–ceramics containing CePO4: orthogonal analysis

CeO 2 was applied as a structure analog to radionuclides that tents to have similar structure such as Np, Pu, and Ce. Element Ce in CeO 2 was immobilized into CePO 4 glass-ceramic with nano-hydroxyapatite (nano-HAP) as a modifier, promoting the fabrication of the ceramic phase. Through the orthogonal method, chemical durability was estimated systematically with the product consistency test (PTC) based on multiple factors. According to the range and variance analysis of the results, the influence degree of the factors follows this sequence: pH > content of nano-HAP > temperature. Moreover, the leaching rates remained around 10 –6 g m −2 d −1 and the mechanism of corrosion is investigated. Graphical abstract
