| Description
| - Morfologie gelu připravených z křemičitanů a titanu pomoci prekursoru byla studována ve všech fázích přípravy, tedy gelace, stárnutí, sušení a kalcifikace. Byly vytvořeny poměrně přesné představy o chování primárních a sekundárních částic při těchto dějích. (cs)
- The morphology of gels prepared from a silica/titania single-source precursor (1), obtained by reaction of 3-oxoethyl-6-trimethoxysilyl-hexan-2-one with Ti((OPr)-Pr-i)(4), was investigated by small-angle X-ray scattering (SAXS) through all stages of the preparation process, that is, gelation, aging, drying, and calcination. The same investigations were performed for mixtures of 1 and Si(OEt)(4). Immediately after the start of the reaction small primary particles are formed, the size of which (r = 0.5 +/- 0.1 nm) remains constant through the gelationand aging process. Anomalous small-angle X-ray scattering (ASAXS) measurements strongly indicate that the primary particles are formed by hydrolysis and condensation of the titanium alkoxide moiety of 1. condensation proceeds by a slower aggregation of the primary particles. Additional Si/O from Si(OEt)(4) is incorporated between the clusters. The size of the mass fractal secondary particles formed by aggregation of the primary particles increases approxim
