"The elastic moduli (Young moduli) of alumina and zirconia ceramics with porosities ranging from almost dense (2-3 %) to highly porous (46-52 %), the latter prepared with starch as a pore-forming agent, have been measured via impulse excitation and four-point bending tests from room temperature up to more than 1200 \u00B0C. It is shown that, independent of the temperature and the material, the porosity dependence of the Young?s modulus is well predicted by our exponential relation and that, irrespective of porosity, the temperature dependence follows a master curve that is characteristic of the material (for alumina exhibiting a decrease with a gradually growing tangent slope and for zirconia exhibiting a steep decrease with an inflection point at moderately elevated temperatures below 400 \u00B0C). Differences between isothermal (static) and adiabatic (dynamic) values are negligible as long as the materials are purely elastic (i.e. at temperatures below approximately 1000 \u00B0C)." .
