Transparent yttria-stabilized zirconia (YSZ) ceramics were sintered with the SPS method in different conditions. The optical and corresponding mechanical properties of the sintered samples were studied. A parameter for optimizing SPS processing has been suggested which characterizes optical transparency versus sample thickness. The dynamic evolution of the swelling areas over time after local indentation of transparent YSZ ceramics was shown. The appearance of spalls from the swelling areas depends on the degree of internal mechanical stresses in the given region of the sample and is explained by the relaxation of stresses accumulated on deformation during static indentation.
