Description
A combination of materials modelling techniques and targeted experimental investigations have identified the manner in which non-stoichiometry is accommodated in both crystalline and amorphous ZrO$_2$. Not only is excess oxygen possible in both crystalline and amorphous ZrO$_2$, but it is found that there is a high propensity for significant deviations–especially in the amorphous system–forming ZrO$_{2+x}$. This has clear implications to the behaviour and degradation of ZrO$_2$ as the boundary oxide protecting zirconium alloys within a water cooled nuclear power reactor.
