Non-linear behavior for chemical expansion in yttrium-doped barium zirconate upon hydration

Research output: Contribution to journalArticlepeer-review

Abstract

The rates of chemical expansion for 20 at% yttrium-doped barium zirconate upon hydration at 100900°C under water partial pressures of 0.008 and 0.023 atm have been studied using combined thermogravimetry and high-temperature X-ray diffractometry. Non-linear behavior for the rates of expansion as a function of proton concentration under equilibrium conditions was observed, suggesting that defect interactions impacted the chemical expansion process.
