Ceramics sintered with nano-rhenium
stabilized zirconia powder for structural ceramics have become one of the main
structural ceramics due to their good properties of phase transformation and
toughening; in the research of nanocomposites, nano-rhenium stabilized zirconia
is used as the dispersion of structural ceramics. Significant effects have been
achieved with enhanced toughening of the substrate.
