Abstract:
The present invention relates to temperature-treated polycrystalline porous Al2O3 bodies comprising an amount of α aluminum oxide of more than 97% by weight, an amount of other oxide alloying components of a total of less than 3% by weight, a macroporosity of between 5 and 30% by volume, wherein the Al2O3 bodies are composed of a plurality of Al2O3 primary crystals comprising a crystallite size of between 20 and 100 μm.
