애플리케이션
Fumed Silica (SiO2) has been used as a precursor to synthesize:
It can be also used in the preparation of:
- Chlorosilanes via silanization, which are used to prepare silica/polydimethylsiloxane membranes to study permeation performance.
- Silicon carbide (SiC) nanoparticles by sol-gel method.
- Calcium silicate hydrate (C-S-H) by treating with CaO and water via hydrothermal reaction.
- Si/PtO2 catalyst for the selective conversion of cinnamaldehyde to cinnamic acid by aerobic oxidation.
It can be also used in the preparation of:
- Silica sulfuric acid catalyst used in the synthesis of 3,4-dihydropyrimidin-2(1H)-ones via one-pot three-component Biginelli reaction.
- HClO4-SiO2 heterogeneous catalyst used in the synthesis of tetrasubstituted imidazoles.
특징 및 장점
Has interesting thickening and thixotropic properties, and an enormous external surface area.
