摘要：
A new zirconia material with increased strength for application as exhaust gas sensor has been developed. This material is codoped with yttria and scandia and has been compared to a reference material doped only with yttria. Both mechanical strength and toughness of the codoped material are enhanced in comparison to the reference material, while the ionic conductivity of the two materials is adjusted to be of same magnitude.
