The limiting current type oxygen sensor is known for excellent characteristics at the low temperatures and throughout the wide oxygen concentration range. In this study, 3 ㏖% Y₂O₃ doped poly-crystal and 15 ㏖% Y₂O₃ doped single-crystal zirconia were used as the solid electrolyte of limiting current type oxygen sensors. The limiting current of the sensor using polycrystalline YSZ was observed over the oxygen concentration range of up to 62.5% and at a temperature range of 560℃∼720℃ in O₂-N₂ mixtures. The sensor using single crystal-YSZ had lower operating voltage than the sensor with polycrystalline YSZ probably due to its low electrolytic resistance.
