Abstract
Tape casting process is used to produce yttria stabilized zirconia(YSZ)substrates.The limiting current type oxygen sensor by screen printing
isostatic laminating and co-fired at 1450℃.The physical characteristics are investigated by X-ray diffractometer and scanning electron microscope.The response time and V-I characteristics of oxygen sensor are tested at 650℃ with the oxygen volume fraction range 0%~90%.The result shows that this sensor has good limitting current platforms in the above range of the oxygen.The response time is less than 9s(the oxygen volume fraction range 20%~75%)and the accuracy can reach 0.5%.
