LAMINATED CERAMIC SINTERED COMPACT AND MEMBER FOR MOLTEN IRON-BASED ALLOY

摘要

PURPOSE:To produce laminated ceramic sintered compact excellent in thermal shock resistance and excellent also in erosion resistance and hardly sticking property to a molten metal. CONSTITUTION:This laminated ceramic sintered compact has a surface layer of magnesium oxide on the surface of the substrate consisting of 35-80wt.% aluminum nitride, 10-60wt.% boron nitride and 0.5-20wt.% one or more kinds of oxides of rare earth elements including Y.
