Abstract

We deposited CeO₂on Haynes 230 substrates via sedimentation deposition. XRD analysis shows that post-heat treatment, the deposits remain CeO₂with no impurity peaks detected. SEM images show granular and porous heat treated deposits. CeO₂grains were seen to coarsen and densify as the heat treatment temperature was increased from 1100°C to 1200°C while retaining a 30 minute soak time. Haynes 230 was shown to have an influence on the sintering behavior of CeO₂grains when heat treated deposits using 1 mg/mL and 0.5 mg/mL suspensions were compared.
