Abstract: Spinel extrudates are produced using a molding composition containing aluminum oxides, aluminum oxide hydrates and metal nitrates. Spinel extrudates are produced by extruding molding composition containing spinel powder and optionally extruding auxiliary aid, stabilizer, shrinkage reducer, and/or pore former. An Independent claim is also included for a honeycomb body obtained by drying the extrudates at 10-200o C, or by freeze drying -40-0o C under a pressure of 0.05-0.8 bar and calcining at 500-900o C.
