| ABSTRACT |
|
The properties of 10 kinds of MgO clinker were investigated to know the effect of MgO clinker's porperties on corrosion of MgO-C brick. For MgO clinker, chemical composition, porosity, density, periclase grain size, and microstructure were examined, while slag corrosion resistance was examined for MgO-C brick. In MgO clinker pore size and it's distribution, periclase grain size, impurities composition and the composition of grain boundaries are more important factors to determine corrosion degree of MgO-C brick than density, potosity and MgO purity. |
