  • Comprehensive performances of carbon nanotube reinforced foam concrete with tetraethyl orthosilicate impregnation: Research indicates significant enhancements in the structural properties of foam concrete, essential for building technology (J Luo et al., 2017).
  • Mesoporous bis (trimethoxysilyl) hexane (BTMSH)/tetraethyl orthosilicate (TEOS)-based hybrid silica aerogel membranes for CO2 capture: Highlights the development of innovative aerogel membranes for effective CO2 capture, contributing to environmental management strategies (YF Lin et al., 2016).

Features and Benefits

TEOScan polymerize in alkaline, acidic, and neutral conditions, making it anadvantageous precursor

General description

Tetraethylorthosilicate (TEOS) is the ethyl ester of ortho silicic acid, which is the most readily available silicon source. It is mainly used as a crosslinking agent in silicon polymer and precursor in the preparation of silicon thin films.
