•SiC and Al2O3 of uniaxial porosity were produced with ice-templating method.•The method allows controlled pore formation within the material.•Calculation of mechanical integrity under irradiation with protons was performed.•Generated thermal stresses should not exceed material’s strength.
New silicon carbide (SiC) and aluminum oxide (Al2O3) of a tailor-made microstructure were produced using the ice-templating technique, which permits controlled pore formation conditions within the material. These prototypes will serve to verify aging of the new advanced target materials under irradiation with proton beams. Before this, the evaluation of their mechanical integrity was made based on the energy deposition spectra produced by FLUKA codes.
