| abstract |
The invention relates to a method for producing thin, porous molded bodies from silicon compound S, wherein, in a first step, a solution or suspension of silicon compound S or starting silicon compound SA is formed in a mixture of solvent L1 and solvent L2, in a second step the solution or suspension is introduced into a mold, in a third step solvent L1 is removed from the solution or suspension until the solubility of silicon compound S in the mixture of solvent L1 and solvent L2 is fallen short of, wherein a silicon compound S enriched phase A and a low silicon compound S phase B is formed and the structure formation thus occurs by means of phase A, and in a fourth step the solvent L2 and residue of solvent L1 are removed, wherein, if silicon compound S is formed from starting silicon compound SA, this occurs in one or more steps which are selected from the first, second and third step. The invention also relates to the molded bodies which can be produced according to the invention and to the use thereof. |
