In this work, trace amounts of alkaline-earth oxide impurities (MxOy), M=Mg, Ca and Al, are identified from different graded ZrB2 based ceramics. The reactions in MxOy-WC systems at high temperature are therefore investigated via X-ray diffraction and element analysis, which have been further suppor...
