摘要：

Thin wall thickness (0.25-0.35 mm) tubes, as tubular electrolytes of solid oxide fuel cells, were successfully fabricated from yttria stabilised zirconia (YSZ) by way of extrusion. Water-based additives and organic additives were studied. An economic and practical process was developed to achieve smooth, linear, and dense ceramic tubes with 2.7-2.8 mm diameter. The microstructures of the selected tubes were examined. This paper describes the fabrication procedure, formulations and optimisation parameters for successfully extruding thin YSZ tubes.
