Abstract
The present invention relates to a porous alpha-SiC-containing shaped body with a gas-permeable, open-pored pore structure comprising platelet-shaped crystallites which are connected to form an interconnected, continuous skeletal structure, wherein the skeletal structure consists of more than 80 wt.-% alpha-SiC, relative to the total weight of SiC, a process for producing same and its use as a filter component.

1-21. (canceled)
A filter including at least one porous, open-pored, gas-permeable alpha-silicon carbide (SiC)-containing shaped body comprising:
- platelet-shaped crystallites connected to form an interconnected, continuous skeletal structure, wherein the skeletal structure consists of more than 80 wt.-% alpha-SiC, relative to the total weight of SiC,
- a porous, open-pored, gas-permeable alpha-silicon carbide (SiC) containing shaped body having an average pore diameter of 3 μm to 50 μm and an open porosity of 45% to 85% vol.-%, relative to a total volume of the porous, open-pored, gas-permeable alpha-silicon carbide (SiC) containing shaped body;
- and
- wherein the average pore diameter of the porous, open-pored, gas-permeable alpha-silicon carbide (SiC) containing shaped body is greater than a size of the platelet-shaped crystallites and greater than an average thickness of pore walls constructed from said platelet-shaped crystallites,
- wherein the shaped body is formed as a honeycomb filter element in which the inflow and outflow openings of the flow-through channels are sealed alternately.
