| Abstract: | An investigation on the amount, the distribution, and the formation mechanism of hercynite (FeO. Al2O3) contained in the ceramic layer of ceramic lined steel pipes is performed by means of theoretical analysis and experiment. As a result,the amount of hercynite is decreased to 5.6 %, and hercynite is isolated in Al2O3 grain boundary to improve the corrosion resistance of ceramic layers. |
