A series of (8YSZ)_1-x(CeO₂)_x (0 ≤ x ≤ 0.3) materials are synthesized by co-precipitation. Both crystalline structure and electrical conductivity of material are detected. (8YSZ)_1-x(CeO₂)_x (0 ≤ x ≤ 0.3) belongs to cubic phase and (8YSZ)_0.9(CeO₂)_0.1 is provided with the highest electrical conductivity. Select 8YSZ as solid electrolyte and (8YSZ)_0.9(CeO₂)_0.1 as dense diffusion barrier to prepare an oxygen sensor by Pt paste bonding method. Limiting current plateau of the sensor is observable at 2% oxygen concentration and at 720–900 °C, and logarithm of the limiting current (log I_L) plays a linear relationship to 1000/T. Limiting current of the sensor is observable at 850 °C and 2–14% oxygen concentration, which is linearly related to the oxygen concentration. The limiting current of the sensor does not vary significantly in the range of water vapor pressure (p(H₂O)) 280.66–2268.63 Pa and in the range of carbon dioxide concentration 0–90%, respectively. The limiting current of the sensor does not decay in the oxygen concentration of 2% at 850 °C during the detection time of 120 h.
