PURPOSE:To provide an oxygen sensor having quick response and composed of an oxygen-ion conductive solid electrolyte containing Nd, Y, F and O at specific ratios and represented by a specific general formula. CONSTITUTION:The raw material of an oxygen-ion conductive solid electrolyte of general formula NdalphaYbetaFgammaOdelta (alpha is 4.5-7.5; beta is 7.5-4.5; gamma is 14-24; delta is 11- 6; 3alpha+3beta=gamma+2delta; alpha+beta=12) is prepared beforehand. The material is formed to a desired form and calcined to obtain the objective oxygen sensor. The sensor has quick response and improved utilizability. |
