One-step mechanochemical approach was used to synthesize nanocrystalline Ce_{1-x}Y_xO_{2-δ} (x ≤ 0.35) solid solutions. X-ray powder diffraction was utilized to characterize crystalline phases of as-prepared products. It was shown that the presence of yttrium suppresses the crystal growth. The effect of yttrium content on the grain size before and after sintering of green bodies at high temperatures...
In this study, 8 mol.% yttria stabilized cubic zirconia (8YSZ) powders as a matrix material and 0-15 wt% BaO powders as an additive were used in order to determine the effect of BaO addition and amount on the microstructure, sintering and static grain growth properties of the 8YSZ. For these purposes, undoped and BaO-doped 8YSZ specimens were annealed for grain growth at 1400, 1500, and 1600C for...
