Abstract

Al2O3-ZrO2 composite powder by sol-gel method was added into fine-particle and ceramic type zirconia me-tering nozzle to prepare modified metering nozzle. The differences in performance of nozzles were studied through XRD, SEM analysis and physical property test. The results are as follows: After modified, density and strength of two type nozzles increase, porosity and stability degree decreases. The thermal shock re-sistance of fine-particle type nozzle improves significantly for the formation of spinel reinforcing phase, how-ever that of ceramic type nozzle don't enhance because microstructure isn't optimized.
