Application

将与十二胺相互作用形成 H+-麦烃硅钠石的插层化合物，并用于混合金属生物活性玻璃的研究。
常用作制备干凝胶的前体
Tetraethyl orthosilicate (TEOS) is an oxygen containing precursor of Si used for the deposition of:
  • Si oxide
  • Oxycarbide
  • Doped silicate
  • Silanol
  • Siloxane polymer
  • Organosilicon thin films

The films can be deposited at low temperatues (<250 °C). TEOS is also used to deposit mesoporous and nanoporous thin films of silica. These porous films can be doped during deposition to further enhance their properties.

Thin films of silicon-doped Fe2O3 were deposited by APCVD (atmospheric pressure chemical vapor deposition) from Fe(CO)5 and TEOS (tetraethoxysilane) on SnO2-coated glass at 415 degrees C. HRSEM reveals a highly developed dendritic nanostructure of 500 nm thickness having a feature

Macroscopic inorganic porous beads are imbibed with a "porous molecular additive" by simple solution processing techniques, resulting in controllable loading and increased surface area. The porous additive consists of soluble organic cage molecules that precipitate as microporous crystals when solutions

Hollow silica spheres with round mesoporous shells were synthesized by core-shell template method, using monodispersed cationic polystyrene particles as core, and TEOS (tetraethoxysilane) as the silica source to form shell. After calcination at 550°C, uniform spheres with a thin shell
