The second layer (33) has the following composition, expressed in wt%: (i) 10-95 magnesium aluminate; (ii) 5-90 magnesium oxide; (iii) 0-20 aluminum oxide. The residue comprises normal impurities. Grains (23) of magnesium oxide are embedded in the matrix of spinel-structured magnesium aluminate, having a mean diameter of 0.1-10 mu m. The first layer (31) comprises yttrium oxide (Y2O3) -stabilized zirconium dioxide. The porosity of the layers (31, 32) exceeds 3 vol%.",
