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 was evaluated by means of scanning electron microscopy. The combination of one-step mechanochemical process and relatively low sintering temperatures resulted in preparation of ceria-based ceramics with wide scale of possible applications.
