The influence of anti-oxidation additions and microstructure characters off used zirconia raw materials on the corrosion resistance of ZrO2-C were studied. The results show that BN addition can enhance the corrosion resistance of ZrO2-C due to the prevention of graphite oxidation,and zirconia raw material with good crystallization and densification will give better corrosion resistance by restrain the reaction between slag and zirconia.
