METHOD FOR PRODUCING A POROUS CERAMIC BODY AND A POROUS CERAMIC BODY OBTAINED FROM SAID METHOD

摘要

The present invention relates to a method for the production of a porous ceramic body comprising the following steps: selecting a first ceramic powder with a first mean grain size; selecting a second ceramic powder with a second mean grain size; selecting a third ceramic powder with a third mean grain size; mixing the first ceramic powder, the second ceramic powder and the third ceramic powder to produce a powder composition comprising at least a trimodal grain size distribution; coating a porous support with the powder composition providing a coated ceramic body; and heating the coated ceramic body to a temperature between 1550-1900°C producing the porous ceramic body.
