1. A method for producing a shaped three-dimensional sintered porous body comprising the steps of:

  • dispersing and suspending a fiber mixture comprising inorganic fibers and a liquid containing an organic binder to form a fibrous slurry;

    applying the slurry to a three dimensional configured mesh sheet comprising through openings distributed throughout and over the surface of the mesh sheet forming from the slurry a wet fibrous three dimensional configured fibrous body comprising the fiber mixture attached to the sheet and complementary to the sheet configuration, the applying step including spraying the slurry onto the mesh sheet and simultaneously de-watering the sprayed sheet to form a de-watered fibrous body;

    drying the fibrous body attached to the sheet;

    removing the binder from the dried fibrous body; and

    subsequently fusing the inorganic fibers to form a sintered porous fibrous body with the three-dimensional configuration.
