Abstract :A comprehensive study was carried out starting from powder synthesis to sintering procedure in order to produce a phase-pure SrCe 0.95 Yb 0.05 O 3 -δ sputter target. In the powder synthesis, the effect of chelating and polymerization agents on the formation of single-phase SrCe 0.95 Yb 0.05 O 3-δ was investigated in detail. In this regard, citric acid, EDTA, and their combinations in different ratios were evaluated as chelating agents. The calcination temperature, ranging from 1000 °C to 1300 °C, was also investigated to reveal its effect on the formation of possible secondary phases. Following the powder synthesis, SrCe 0.95 Yb 0.05 O 3-δ sputter target with dimensions of ~50 mm diameter and ~3 mm thickness was produced by powder pressing with deformable compaction die and the subsequent sintering at 1300 °C for 10 hours. A relative density of 0.95 was achieved in SrCe 0.95 Yb 0.05 O 3-δ targets as a result of the procedure in question without the use of a sintering aid.
