Original Abstract

An alternative approach to the thermal etching of oxide ceramic materials (α-alumina, t-zirconia, and c-zirconia) is presented and compared with the standardly used regime for thermal etching. The given approach was tested on partially (93.8 - 96.3 % t.d.) and fully (99 – 100 % t.d.) dense samples with the criterion of minimizing the density difference after and before etching and with the criterion of clear visibility of grain boundaries. The presented results show, that 900 °C/1 h etching regime is sufficient to reveal the studied microstructure for analysis of the surface of the samples sintered above 1355 °C without affecting the density and without thermal effect on the measured average grain size. The modern approaches as digital analysis of the images can help to reveal the thin grain boundaries after thermal etching at low temperatures.
