CERAMIC COMPOSITION, CUTTING TOOL, AND TOOL FOR FRICTION STIR WELDING
An object of the present disclosure is to improve the properties of a ceramic composition. A ceramic composition contains alumina (Al2O3) and tungsten carbide (WC) and is characterized in that an atomic layer formed of at least one element selected from among transition metals belonging to Groups 4 to 6 of the periodic table, yttrium (Y), scandium (Sc), and lanthanoids is present at a crystal grain boundary between an alumina (Al2O3) crystal grain and a tungsten carbide (WC) crystal grain.
