Radiation induced amorphization resistance in A2O3-BO2 oxides

Much work has been devoted in recent years to identifying ceramic materials that can withstand high doses of radiation without incurring excessive defect accumulation, or suffering undesirable transformations such as amorphization. In this paper, it is proposed that a large range of A2O3-BO2 oxide compositions, with structures related to the fluorite crystal structure, may exhibit exceptional resistance to radiation-induced amorphization. Results of heavy ion irradiations on selected A2O3-BO2 oxide compounds are presented in support of this prediction
