The present paper aims to briefly summarize our recent experimental data of the doping effect on the high temperature plastic flow in 3mol% Y2O3-stabilized TZP (3Y-TZP) and Al2O3, and to show that change in chemistry of grain boundaries is responsible for the doping effect.
Grain Boundary Structure in Oxide Ceramics.
The present results indicate that the high temperature plastic flow in TZP and Al2O3 is strongly influenced by chemistry in the grain boundaries.
The present study is probably the first trial to explain the doping effect on the high temperature plastic flow in oxide ceramics in terms of the chemistry in the grain boundaries.

The tunability of the electromagnetic properties, considered until now as a matter of chemistry, strictly depending on the synthesizing process and studied by experimental methods with enough precision at frequencies no higher than a few MHz, can be reached by the 3D simulation methods, which reproduce the structure and simulate the interactions between constituents and with external fields at any frequencies.
The 3D simulation methods, which reproduce the structure and simulate the interactions between constituents and with external fields at any frequencies, offer the possibility to indentify and choose the optimal control parameters at structure level.
