precursor for a ceramic filter and ceramic filter

摘要

precursor (10) for a device for filtering, comprehensively: at least two layers (20) of a filter element, and each position of the filter element a variety of three-dimensional cages (22) includesin fixed relationship are linkedeach of the three-dimensional cages (22) through a large number of segments of a material is formed, and each segment of an edge of the geometric solid is undwobei minimum;10% of the segments, at least one flu00e4chenunregelmu00e4u00dfigkeit which, from the segment covers, the segregating of the coating material are improved.
