[origin: EP1199520A1] Thermal shield comprises a hot side subjected to a hot medium and a wall side lying opposite the hot side; a hot side region bordering the hot side; and a wall side region bordering the wall side. The grain size in the wall side region is less than in the hot side region. Preferred Features: The grain size in the wall side region is 0.4-0.9, especially 0.6-0.8 less than in the hot side region. The grain size in the hot side region is 1.5-3.5, especially more than 2 mm. The shield is made from aluminum oxide and aluminum silicate, in which the concentration of the aluminum oxide is greater in the wall side region than in the hot side region.
