Abstract
Disclosed is a process for the production of a porous granulated ceramic material with a pore size greater than 1 mm, in which clay is mixed with calcite, quartz sand, dolomite, feldspar, fireclay, kieselgur and/or sepiolite as aggregate material, with water, with a fluidizer and with a surface-active agent and foamed in the usual way. The foamed mixture is subsequently moulded, if required, to form clay mouldings, the mouldings dried at a temperature between room temperature and 200 DEG C, the dried mouldings crushed and sieved, if required, the sieving fines being returned to the starting mixture, and finally the mouldings or crushed mouldings within a given particle-size range roasted at a temperature above 600 DEG C. The porous material thus produced is intended for use as a plant substrate. The starting materials are added to the mixture in given proportions and the mouldings or crushed mouldings with a residual moisture content of 5-25 % are placed in a preheated oven and roasted at a given temperature in the range between 750 and 1050 DEG C. This invention also includes the subsequently manufactured plant substrate, as well as the new use for this product.
