A partially stabilized zirconium oxide nozzle to he used in a continuous copper casting process has been designed to adequately resist thermal shock and satisfactorily tested in the operating environment. The zirconia has an optimized stabilizer content in terms of free thermal expansion characteristics and high temperature tensile strength. The optimization is achieved through control of composition, microstructure, and crystallographic transformation during the heating cycle. Thermal and stress analyses of the design indicate a positive safety margin subsequently borne out by production testing.
