Abstract

Synthetic pyrochlore samples Y₂Ti_2-xSn _xO₇ (x=0.4, 0.8, 1.2, 1.6), Nd₂Zr ₂O₇, Nd₂Zr_1.2Ti_0.8O ₇, and La_1.6Y_0.4Hf₂O₇, were irradiated in-situ using the IVEM-TANDEM microscope facility at the Argonne National Laboratory. The critical temperatures for amorphisation have revealed a dramatic increase in tolerance with increasing Sn content for the Y ₂Ti_2-xSn_xO₇ series. This change has also found to be linear with increasing Sn content. Nd₂Zr _1.2Ti_0.8O₇ and La_1.6Y _0.4Hf₂O₇ were both found to amorphise, while Nd₂Zr₂O₇ was found to be stable to high doses (2.5×10̂15 ions cm^-2). The observed results are presented with respect to previously published results for irradiation stability predictions and structural disorder.
