摘要

The zirconia metering nozzles prepared from magnesia partly stabilized zirconia were researched in this paper.The operational environment of zirconia metering nozzles was simulated by keeping metering nozzles at 1 540 ℃ for 5 hours, and then the nozzles were quenched in water to keep the phase composition at high temperatures.The analyzing methods were X-ray diffraction and scanning electron microscope (SEM).The metering nozzles after water quenching were compared with the same kind of metering nozzles after slow cooling according to the actual technical process in terms of mineral composition and microstructure.The results show that for the zirconia metering nozzle after stow cooling, the c-ZrO2 and m-ZrO2 contents of are 41％ and 59％, respectively;for water quenching, c-ZrO2 and m-ZrO2 contents are 57％ and 43％, respectively.So, in the process of casting about 16％ of m-ZrO2 is transferred into c-ZrO2.Compared to the phase composition of the ex-factory products, c-ZrO2 content increases by 39％.The effect of phase transformation on the product performance still needs a further research.
