| 摘要 |
The invention proposes a method for the making of an inorganic porous membrane applied onto a suitable carrier, such that for the shaping of a suitable covering onto this earner one starts with a by itself known starting sol, which is obtained by reacting in a suitable ratio of an organo-silicate and a methylated silane and cooling of the reaction mixture, whilst every covering step, executed with this reaction mixture, will be followed by a sintering step, for which according to the invention a strong dilution of this sol is used for at least the first covering step onto the carrier, and a modification of this sol, obtained by adding at least one material with low surface tension for improvement of the wetting by and the mobility of the sol particles, is used for the subsequent covering step(s). Each covering step is followed by a sinter treatment.
