| Abstract: | A sol-gel process is described for the preparation of diphasic composite materials. The method involves the growth of extremely fine crystalline or non-crystalline materials inside a pre-made gel structure (of SiO2) by soaking the gel in metal nitrate solution and subsequent precipitation of the metal with the selected anions (using mineral acids) followed by a densification step. |
