Originální abstrakt

Phase and chemical compositions are crucial for properties of advanced ceramic materials. A study of the phase and chemical composition is nowadays limited to localized 2-dimensional methods and their sensitivity to local changes. Alumina as the most used ceramic material is often doped by MgO to prevent abnormal grain growth. The phase equilibrium of Al 2 O 3 and MgO has been widely studied and discussed. However, the chemical composition of spinel (MgAl 2 O 4 ) in three dimensions has never been described. Here we present a TOF-SIMS analysis of spinel in an alumina matrix, where chemical composition in 3D is demonstrated. The presented analytical method allows characterization of advanced ceramic materials in volume and study of grain formation and contamination in nanoscale.
