Description :

Tetramethoxysilane most commonly used as starting materials for sol-gel. Polysilicic acidesters are condensation products obtained by incomplete hydrolysis or orthosilicic acid esters. They are also be used as starting materials for the sol-gel process. Tetramethoxysilane typical application: Be hydrolyzed to form silicon dioxide (silica). Crosslinkers in silicone rubber systems
Drying agents in sealing compositions
Inorganic binder for refractory fillers and pigments
Coating material for pigments, fibers and other surfaces

Vibrational spectral/structural changes from the hydrolysis/polycondensation of methyl-modified silicates. II. Comparisons for condensates from the binary diethoxydimethylsilane/tetramethoxysilane system 2019/06/17

Comparisons were made for the structures of condensates from the tetramethoxysilane (TMOS)/diethoxydimethylsilane (DEDMS) system upon hydrolysis/polycondensation using infrared and Raman spectra. Spectral data indicated that all generated condensates possessed four-membered (Siz.sbnd;O)4 rings as st...

Mullite formation from gels derived from tetraethoxysilane or tetramethoxysilane with aluminium sec-butoxide 2019/06/17

Rice hull ash (92% SiO2 purity), when loaded with 5 wt.% of potassium hydroxide, reacts with dimethyl carbonate at 625 K to give almost quantitatively tetramethoxysilane. The ash also reacts with diethyl carbonate to give an 80% yield of tetraethoxysilane at 725 K....

Tailoring structure and properties of silica aerogels by varying the content of the Tetramethoxysilane added in batches 2019/06/16

Silica aerogels with high optical transparency and ultra-low thermal conductivity are ideal candidates for energy-saving windows. Often such applications require rather exquisite control of microstructure (i.e., cluster size and cluster packing geometry). In this research, a series of silica aerogel...

Functionalization of mesoporous silica by condensation of tetramethoxysilane and alkyl peptidoamine monomers in the presence of a non-ionic fluorinated surfactant 2019/06/15

The functionalization of mesoporous silica materials with alkyl peptidoamines by the co-condensation method was investigated. Alkylpeptidoamines were introduced via aminopropyltriethoxysilane (APTES). Samples are prepareds by using a nonionsc fluorinated surfactant C8F17C2H4)9OH. Results obtained by...

Molecular structure, force field and vibrational spectra of tetramethoxysilane 2019/06/13

IR and Raman spectra of Si(OCH3)4 and Si(OCD3)4 are reported and the peak assignments discussed. The equilibrium molecular geometry calculated by ab initio gradient methods agrees with the structure flattened along the S4 axis, established by an electron gas diffraction study. The initial force fiel...
