The Properties of YSZ-Ni-Cr Cermet Fabricated by Sol-Gel Method

Abstract:

The properties of YSZ-Ni-Cr cermet fabricated by Sol-Gel Method（YSZ-Ni-Cr powder was synthesized by coprecipitation method at 850°C for 2 h and was processed into YSZ-Ni-Cr cermet by hot-press sintering at 1350°C for 1 h）was explored. The identification of phases was carried out using a X-ray diffractometer (XRD). The particle size and morphology was determined by electron microscopys(SEM/TEM) The conductivity had a tendency to decrease with increasing temperature. This behavior can be accounted for that there are two conduction paths through the cermet, an electronic path through the (Ni,Cr) metal phase and an ionic path through the ZrO2-Y₂O3 phase.
