The invention relates to a method for producing a monolithic, porous, ceramic shaped body and to the shaped bodies produced according to this method. Said shaped body is used predominantly as a support material for porous, inorganic and/or organic membranes for the flow filtration of liquids and gases. The aim of the invention is to provide a method for producing a shaped body consisting substantially of TiO 2 with an open porosity >10%, an average pore size of between 1 and 50 μm and a mechanical stability >20 N/mm 2 . To achieve this,...
1. Method for producing a monolithic, porous, ceramic shaped body from TiO 2 having a mean pore size of 1-50 μm and a porosity of >10%, comprising pre-sintering a first TiO 2 — powder part at temperatures>1200° C., and subsequently reducing the first TiO 2 powder in size to a screening refuse of <5% at grain sizes smaller 100 μm, adding to and mixing with this granulate at least one further part of TiO 2 -powder, the grain size of said further part being ≦0.5 μm, whereby the grain size of said furth...
