Abstract
The present invention relates to a method for production of a porous ceramic body and a corresponding porous ceramic body which can find application, in particular, as filter, or filter membrane in cross-flow filtration. According to the method of the invention, a bimodal ceramic powder mixture is moulded to give a moulded body, which is subsequently recrystallised by conditioning at high temperature, such that the fine particles melt and link the large particles firmly together by deposition thereon, such that, in defined regions (), a porous ceramic body with a homogeneous structure of almost uniform particle size and pore size is formed, whereby the pores provide an interconnected, open, three-dimensional network.
