Abstract
The invention relates to a process for the manufacture of tiles having a porous surface and a dense surface pore radius distribution, and the application of said tiles as the substrate for fixing or immobilizing indicators, catalysts, biomasses or parts of biomasses. The tiles are coated with small particles of equal size in a dense particle size distribution of a material capable of agglomeration without the application of pressure, without the addition of a binding agent and at temperatures below 120C, with the result that the cavities between the small particles of equal size on the surface of the tiles form pores with a dense pore radius distribution. The shape and size of the pore radii are defined by the shape and size of the small particles of equal size, and the pore radii distribution are defined by the particle size distribution.
