Electrical conductivity of zirconia for flow channel inserts in contact with liquid Pb-16Li

Popis výsledku v původním jazyce

Flow channel inserts (FCI) as functional components are being developed for the Dual Coolant Lithium Lead breeding blanket. Since the aim is to electrically decouple the main flow of liquid lead lithium and a steel structure of the blanket, knowledge of electrical properties of the FCI materials is crucial. For this purpose, series of direct electrical current measurements were performed on oxide ceramic - ZrO2 in a form of yttria stabilized zirconia. Initially, the electrical conductivity was determined in temperature range of 240-520 degrees C in an inert oxygen-free atmosphere using two working electrodes on the opposite sides of a flat sample. Subsequently, the electrical properties of the samples were determined using liquid Pb-16Li as a substitution of one of the electrodes, under otherwise identical experimental conditions. The electrical conductivity of materials in the given temperature range is well below the required limit of the Flow channel inserts.
